Hi Keithwalker I see you added a Families column and I think it is a good idea since arguably number of Families is a better indication of how prolific an inventor is. Thanks for doing this! However, expanding on what I said previously. There are several examples where an inventor is in top 100 by number of patents but not even close by number of families. let's take an example of Jack Kavalieros, with 523 patents he is not in top 100 inventors but with 347 families he likely would be. Conversely, Austin L. Gurney is in top 100 by number of patents but with just 276 families would not be in top 100 by number of families. Now that everything is automated, how about taking the old list (e.g. inventors with > 200 patents), then filtering top 100 separately by each of patents and patent families, and then combining the two? the resulting table will have a bit more than 100 entries but probably not by much, and would never grow to more than 200 entries. I'd help code this up but I don't know where your scripts are - you mentioned they are in python, want to push them to github/gitlab? Thanks! — Preceding unsigned comment added by 2.52.151.85 (talk) 08:24, 5 January 2023 (UTC)


 * At present I am opposed to the proposal to combine lists but will reassess after I complete projects that would be a prerequisite and are needed regardless: 1) Figuring out how to resolve the current "NA" family counts for pre-digital patents. 2) Writing a USPTO link converter and then manually verifying and correcting each of the remaining 235 inventor refs. Keithrwalker (talk) 18:25, 5 January 2023 (UTC)
 * 1 - I feel just assuming family count == patent count in this case would be sufficient - I did a quick look and none of the patents I could find looked like it was a continuing application (contained the same disclosure). These were probably unusual at that age but I could not quickly find out more.
 * 2 - what is meant by "Writing a USPTO link converter and then manually verifying and correcting each of the remaining 235 inventor refs." what would you like to convert to what and what would you like to verify? 2.52.20.248 (talk) 14:36, 29 January 2023 (UTC)
 * 1 - I thought the same thing, but found the assumption to be incorrect. When looking at a few of Edison's patents, I quickly found one marked as a continuation in the specification. I have 7 inventors with an NA on the article and 5 on Talk, representing 8,975 patents that are a mystery in this regard. I can't make an assumption, guess at a percentage, nor do original research to get a manual tally. This needs a proper source, which I have yet to find.
 * 2 - I completed this project, which you can see on the Talk page. Keithrwalker (talk) 19:04, 30 January 2023 (UTC)
 * Could you give an example for Edison please? I have some ideas :) 2.52.144.173 (talk) 19:33, 30 January 2023 (UTC)
 * 1,377,194 titled "STORAGE BATTERY." Lines 14-19 state, "This application is to be regarded as a continuation of my copending application, Serial No. 324,058, filed September 16, 1919, entitled Storage batteries, as to all subject matter common to both applications."
 * If you are thinking of doing word parsing to subtract continuations from patents to get families, there are a few hurdles. First, I doubt there is a parse-able source for all inventions for all 12 inventors. Second, they may not all use the convention that Edison used in this one example. Third, they need to also parse divisionals, which like continuations share a family with the original. Of the about 20 patents of Edision I just looked at, one was a continuation and three were divisionals. But more on divisionals in the next paragraph. Fourth, any word parsing should not inadvertently consider continuation-in-part patents because they are new inventions, albeit closely related to another patent, and the USPTO gives them their own family number.
 * To see an example of an Edison divisional, look at 1,908,830 titled "HOLDER FOR ARTICLE TO BE ELECTROPLATED." Divisionals are like continuations in that they have the same family number as the original filing. But unlike continuations, divisionals generally represent separate inventions (i.e., the inventor or assigned company tried to get multiple inventions for the cost of one filing, but the agency rejected it and required it be divided). Therefore, families should not be used to suggest how many inventions one has. For that, the best we could do is add originals (including continuations-in-part) to divisionals and ignore families and continuations. Keithrwalker (talk) 01:47, 31 January 2023 (UTC)


 * A separate Families table would be problematic for several reasons, but I'll look to add a Families column to the existing table as it is an interesting stat for the most prolific inventors. People can click column headers if they want to sort by Families.

I understand. The issue that worries me is that top 100 by # of families might be different than top 100 by patents. So if I'm interested in top 100 by number of inventions one might not be interested in number of patents since it's a technicality. Maybe just make the table bigger? There's no strict necessity to just include 100 people as long as top 100 are there, more info is always better than less :) . — Preceding unsigned comment added by 2.52.151.85 (talk) 09:01, 27 December 2022 (UTC)

Hi Keithrwalker, finally had time to look at automation. Here's an example for Rinaldo-Jr-John. You can tweak queries as you like. For other inventors you would tweak it accordingly. I don't know why you have to repeat the query 3 times but oh well. To avoid conflicts I propose simply two tables: most prolific inventors by # of patents and most prolific inventors by # of patent families And simply explain that the table by patent families does not include older inventors due to lack of data.

And just to note, ATM links all seem to include useless "A or B1 or B2" which does not seem to affect the query at all - I am guessing it works simply because "A" appears for sure somewhere in almost any patent application. Just (lastname-firstname).in is typically enough. If there are alternate spellings you can include that and $ seems to work as a wildcard. For really complex cases (lastname-firstname).in NOT (badlastname-badfirstname).in — Preceding unsigned comment added by 2.52.151.85 (talk) 23:12, 26 December 2022 (UTC)


 * This is fantastic! I can't express how thankful I am to you for figuring out a method to query data. For years I had this automated, USPTO broke that in their recent platform change, but then you figured out the key to restoring the automation. My Tuesdays are about to become much less hectic and stressful like they used to be. :)
 * I've made good progress this evening converting this to Python and structuring in a way that works with the rest of my automation. I'll be able to use this to pull in patent count, family count, and most recent issuance date. Will likely not be ready for tomorrow because I need to debug an I/O issue and write a function that converts inventor URL into the query syntax needed. I also need to look closely at family count for inventors who span and come before pre-1976 digital records to make sure it works as expected.
 * A separate Families table would be problematic for several reasons, but I'll look to add a Families column to the existing table as it is an interesting stat for the most prolific inventors. People can click column headers if they want to sort by Families. I might have to shorten some of the headers. Will also investigate if there is a ratio of families to patents or similar calculation to include. I am unsure if that would be of interest, but once I analyze the data, perhaps it may reveal interesting trends like there is when sorting on the Inventors / Patent column.
 * The "A or B1 or B2" is needed. If you look closely you'll see it isn't a simple string search of the entire patent application but instead queries just the "AT" field (i.e., "Kind Code Search and Application Type"), which is how we limit results to utility patents. It will appear to do nothing for inventors who only have utility patents. Here is the reference of fields (USPTO calls them "indexes".) https://ppubs.uspto.gov/pubwebapp/static/pages/searchable-indexes.html Keithrwalker (talk) 06:26, 27 December 2022 (UTC)

Hi Keithrwalker, I wonder whether it's useful to (also?) rank inventors by number of patent families. Counting patents might count e.g. continuation patents where no new invention is claimed, separately. Thanks! — Preceding unsigned comment added by 209.132.186.246 (talk) 11:08, 12 December 2022 (UTC)


 * If you can identify a way to do that through the USPTO Patent Public Search at https://ppubs.uspto.gov/pubwebapp/, that would be of interest as an additional column. The closest I have found is using "NOT CONTINUATION.COND.", but this only works for 2006 and newer. There is the FMID index for Family ID that might work if there were an option to specify uniqueness. There is a PARN index for Parent Case Information that might work if there were an option to compare with NULL. We would also need some way to apply the same for pre-digital patents unless we left it as NA, which would be unhelpful for sorting. Keithrwalker (talk) 17:10, 12 December 2022 (UTC)
 * What we would also need is ability to automatically retrieve the data. The USPTO's recent change to their query system broke the Python and BeautifulSoup aspect of my automation. I now have to manually click and record inventor counts and update a timestamp for each inventor every week, and USPTO searches are very slow in their new system. This would double the time required if we added such a column, hence requirement for automation. Keithrwalker (talk) 17:36, 12 December 2022 (UTC)

Hi Keithrwalker, I was wondering how you got 513 patents for Clyde C. Farmer. If I follow the link I end up on google patents page which shows "about 525 results". Thanks! — Preceding unsigned comment added by 2.52.21.254 (talk) 11:31, 22 November 2022 (UTC)


 * Prior to the existence of Google Patents, Clyde was listed on an article that claimed he had 513. For inventors who predate digital records, we generally have to rely on such articles. I see the 524 at Google Patents (one of the 525 was for Clyde H Farmer). I updated the ref and the count in my tracking spreadsheet so the next time I update the Talk page, it will get updated. Thanks for bringing this to my attention. Keithrwalker (talk) 21:40, 22 November 2022 (UTC)

Hi Keithrwalker, thanks a lot for your hard work. Question #1: can you runa script to extract PCT data base. it includes some high value patents you may missed in this list. Question #2: how to determine the citizenship of a inventor? do you need manually modify it? what if we want to change the citizenship to China 🇨🇳? thanks a lot best Su — Preceding unsigned comment added by Suliu1 (talk • contribs) 03:22, 14 September 2022 (UTC)

Hi Su, Answer #1: Thank you for the recommendation! I will investigate to see if the PCT database can be used for the article. Most sources cannot, but I would love a better source than we currently have. USPTO is incomplete (e.g., I have patents that only issued outside the US) and problematic (e.g., my middle initial is a typo on one, there is more than one inventor with my name, my name is inconsistently listed, other data such as residence and assignment are similarly a mess, there are limitations of the search, etc.), but is nevertheless the best source for most inventors' ref. For some inventors we use a different source. As for the "high value patents" comment, please see the "Significance of inventions" section on the article. We do not consider nor imply anything about patent value in this article.

Answer #2: We do not list citizenship on the article. See the definition that appears below the list. Citizenship would require original research and we have no ability to claim citizenship from an authoritative source except in very few cases. Instead we use the inventor's country of residence listed on their most recent patent, which is objective and consistent albeit of questionable value. I generally only set this when I add an inventor to the article, and so if you see an inventor has moved, please update the article. Using the majority country or most recent 50 would probably be more meaningful -- just there is rarely any difference, the data in some cases defies automation, and therefore I can't justify the development time and resulting hammering of the USPTO web site. --Keithrwalker (talk) 07:25, 14 September 2022 (UTC)

Addition of Deepak Sekar
Thank you for keeping the prolific inventors page updated. Can you please add Deepak Sekar? He got to 200 issued utility patents this week. The USPTO search query is APT/1 AND IN/Deepak AND IN/Sekar Here's a link to the search results. Nationality is USA. — Preceding unsigned comment added by David.s.dalmia (talk • contribs) 22:04, 10 June 2022 (UTC)

Thanks for the heads up. Deepak does not yet qualify, but I will monitor and add him to the article when he does. The reference you provided includes multiple Deepak Sekar inventors who reside in different countries (Australia and India), who don't invent in the tech area that the prolific Deepak invents in, and a patent with inventors Nivas Sekar and Deepak Dhanapal and not Deepak Sekar. This is the reference I came up with that seems to include just the prolific Deepak Sekar, although I'm still uncertain because this is a very common name. Please inspect this query and respond if any patents returned with this search are not Deepak's, if it omits any that are, and if there is a way to optimize the query without accidentally pulling in other inventors: https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2FSekar-Deepak$+and+an%2F%283D+or+SanDisk+or+Hefei+or+Rambus+or+Georgia%29+or+pn%2F9000557 --Keithrwalker (talk) 02:41, 11 June 2022 (UTC)


 * Thanks for your thoroughness and diligence. Your points are valid on the names and the Australia and India locations - checked with the inventor just now. The other patents in the list are his, he confirmed. I would suggest making an edit to the search query based on the inventor's background - added his past work affiliation with chowbotics, which was acquired by doordash.

Possible Addition of Jian Gao
Really appreciate that you keep these page up to date. From Dell internal Patent report, it shows Jian Gao from Beijing, CN got 203 U.S Patents granted. Actually there are multiple "Jian Gao" in Beijing hold U.S patents.. the in request Jian, all his patents filed from EMC, Dell EMC or Dell Technologies. not sure how the filter can be setup. thanks.

--- Thank you for letting me know! I added Jian to the article. With an impressive filing rate of 34 a year, Jian will no doubt rise fast in the list of prolific inventors. If you find a better ref for Jian, let me know here or you can update the article. I found 202 with this ref: https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2FGao-Jian+and+an%2F%28Dell+or+EMC%29

If you know of any other prolific inventors at Dell who are over 200 or are filing a lot such that they might some day reach 200, please let me know. So far we just have Jian and Assaf Natanzon for Dell --Keithrwalker (talk) 05:15, 12 January 2022 (UTC) --- Please kindly watch these names from Dell, all of them with at least 150 granted: Arieh Don; Philippe Armangau; Jean-Pierre Bono — Preceding unsigned comment added by 152.62.44.202 (talk) 17:04, 12 January 2022 (UTC)

Addition of Johan Rune and Icaro Da Silva
It looks like James Pratt of Round Rock, TX has recently passed the 200 utility patent mark. There are quite a few James Pratts, but James is at AT&T and it appears all of his patent work shows Round Rock, so hopefully you can set up the filters easily.

Thanks. Will add to the article tonight. --Keithrwalker (talk) 21:54, 20 September 2021 (UTC)

Please check Johan Rune from Ericsson/Sweden

Another one is Icaro Leonardo da Silva, I am almost sure he makes the list, but was not sure which of his names to use for the search

Thank you! I'll add Johan Rune. Icaro da Silva has 125 with: apt/1 and in/(da-silva-icaro$ or dasilva-icaro$). I did some wildcard research on just "icaro," and unless any of his patents don't include "icaro," 125 is what he has. I'll add him to the Talk page because it is quite possible he'll make it. --Keithrwalker (talk) 03:27, 8 August 2021 (UTC)

Thanks for letting me know! Unfortunately, your USPTO query is incorrect. If you query on in/john and in/mese you will find you have inadvertently included patents that are not for John Mese, such as those where relatively prolific inventor Murat Mese invented with someone named John. The correct query shows only 193. I'll add to the article's Talk page and move to the article when 200 is reached, which should probably not be long. --Keithrwalker (talk) 19:14, 10 July 2021 (UTC)

I'll look into these hopefully for next week. I tried to work on this now for tonight's data pull, but USPTO site is giving lots of intermittent database and web server errors that make research impractical. I am not even sure it will be working well enough tonight for the automated pull. I researched Walter Muller and can say he doesn't meet the criteria and is unlikely to unless he resumes inventing. He only has 127 that I can find without much momentum. If you saw more, that is because there is more than one Walter Muller. I was in progress on Iana's and then gave up. --Keithrwalker (talk) 22:22, 27 October 2020 (UTC)

USPTO site is working today, and so I processed the list. I added Paul Marinier, Robert Baldemair, Iana Siomina, and Daniel Larsson to the article. Someone else has added Parkvall Stefan. I added Fredrik Gunnarsson to the Talk page and will add to the article when he soon qualifies -- there are two inventors with the same name, and the inventor from Ericsson currently has 195. --Keithrwalker (talk) 15:57, 28 October 2020 (UTC)

His American patents are around 150 but worldwide he has over 400 https://worldwide.espacenet.com/searchResults?DB=EPODOC&IN=%22Bradbury+Jonathan%22+or+%22Jonathan+Bradbury%22

I think that query is right, but if I am mistaken let me know. — Preceding unsigned comment added by Doesthislookwright (talk • contribs) 21:08, 13 February 2020 (UTC)

Thanks, Doesthislookwright! I will add Jonathan when he qualifies. He currently has 153 issued utility patents and needs 200 to be included. Espacenet does not show only issued utility patents due to its nature and has many false positives due to its search engine. For example, if some patents have co-inventors Jonathan Jones and Raymond Bradbury (I made these names up), your search for Jonathan Bradbury will include them despite that not being what you meant. Use this reference instead, which also omits the several patents by a non-IBMer who has the same name. http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2FBradbury-Jonathan$+and+an%2Finternational Keithrwalker (talk) 04:13, 14 February 2020 (UTC)

Hello Keithrwalker, I am new to wikipedia (user account made this morning) but interested in inventors and often visit this page. I wanted to suggest an edit. Valentina Salapura from IBM Research has at least 348 Patents. The list below is from 2004 - 2019. http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2Fsalapura-valentina$

If this sort of information/suggestion is useful I would be happy to send any others I come across.

Doesthislookwright (talk) 16:17, 5 November 2019 (UTC)

Thanks! I will add Valentina in today's table update and look forward to any additional inventors you can find. If you work for IBM like the inventors you are adding, you can find me in Bluepages if you know of other inventors that need to be added or if you want me to monitor any that will reach 200. --Keithrwalker (talk) 05:16, 6 November 2019 (UTC)

Suggested Addition of Vijay Narayanan
Narayanan is a Fellow & Strategist working in the area of Physics of AI at IBM Research. http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2FNarayanan-Vijay$ public research Profile - https://researcher.watson.ibm.com/researcher/view.php?person=us-vijayna

Doesthislookwright (talk) 22:32, 5 November 2019 (UTC)

I will add Vijay. There are multiple inventors with the same or similar name. This ref omits the other inventors: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2Fnarayanan-vijay+andnot+an%2Fmicrosoft+andnot+an%2Ffair

Correction of Thomas J. Kennedy III inventions
Mr. Walker, thank you for your vigilance on the Wikipedia page for prolific inventors. My query was flawed and did pick up one patent that was not mine. I was just issued US Patent 9,272,234 as a co-inventor for "SEPARATION OF MULTI-COMPONENT FLUID THROUGH ULTRASONIC ACOUSTOPHORESIS". Based on the query that you posted,: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2F%28kennedy-thomas$+or+kennedy-III-thomas$+or+kennedy-II-thomas$%29+and+ic%2F%28wilbraham+or+chicopee%29, I believe that this puts me at 200 US utility patents. I am not as adept as you at editing the Wikipedia pages so, I can add my name back or I will leave it to you to add back my entry. Also, I read several of your patents that are assigned to IBM. Impressive. And, yes, Mike Sullivan and I worked together at Spalding Sports Worldwide. We were taught the art of patents by Robert Molitor, the inventor of the two piece golf ball as well as several other inventions.Tjkennedy3 (talk) 15:16, 1 March 2016 (UTC)

- not much familiar with wikipedia and wanted to share this. not sure if useful or how to share it.

Prolific inventor statistics Here we are looking at the statistical distribution of the inventors. We know that there are about 10,000,000 patents issued in the US since the recording of patents started. Of these patents according to the patent office 90% are utility patents therefore 9,000,000 US utility patents. Also according to the patent office there are on average 2 inventors par patent making it 18,000,000 names of inventors listed on utility patents, few of which are names of prolific inventors with names repeated many times. At a start we would say that we have a set A = 18,000,000 of inventors who have at least one patent each. If we want to look for prolific inventors with at least a number n of patents, then this group G(n) is defined by the equation G(n) = A/n2. So
 * For inventors with at least 3 patents for example, we have a group G(3) = 2,000,000 inventors
 * For n=200 patents like in our list then G(200) = 450 inventors . I guess in our list we have about 200 names so we must be about half way.
 * For n=500 patents then G(500) = 72 inventors . Our list has 65 inventors with over 500 patents so we must be close to having most of them.
 * For n=1000 patents then G(1000) = 18 inventors. Our list has 13 inventors with over 1000 patents.
 * For n=4000 patents then G(4000) = 2 inventors. We right on the money.

Of course these are statistically approximations. All4dz - All4Dz, the math does not work due to a number of factors. We also could not include any such distribution on Wikipedia since it would be regarded as original research due to how much guessing there would be on our part and a lack of a reliable source.

There are more variables needed, none of the variables are constant, most cannot be discovered, and the rate of change for each variable cannot be defined. Some variables have grown near linearly (like average number of inventors ), but will stagnate at some point and likely decline and then fluctuate. Some have seen rate increases recently (like patents per year ), but vary through history and are sensitive to business models, laws, and budgets, and thus cannot be defined.

There are fewer than 18 million inventors. If you use a closer guess into the algorithm (and it will be a guess -- I would say likely no more than 4-5 million), the distribution doesn't match what we see. You can venture a closer guess by considering one study estimated the number of unique inventors from 1975 through 1999 to be 1,565,780 based on the NBER Patent Data File matched with SOUNDEX coding. However, upon reviewing their methods in light of data inconsistencies and errors I have seen that they did not account for, I am sure their number is too high. Now extrapolate out the dramatic rate increase of patents since 2009 counter-balanced by a likely increase in repeat inventors (thanks to savvy business models that encourage that -- although I have no source and at this point it is just a theory), and we are far less than 18 million unique inventors.

We also need to consider that some data is outside the USPTO and that some includes or does not include data before 1975. Keithrwalker (talk) 04:42, 22 July 2018 (UTC)


 * Hi Keithrwalker
 * first let me thank you for all the great work you are doing in keeping this page up to date and relevant especially with all the change to the patent office software lately.
 * I have a certain number of issued patents under my name in the USPTO. However, I have extra number patents in my early time in Japan under my japanesed name then. I am wondering if I have to add them to my list of patents here. Just wondering.
 * here a link if interested to see https://www.freepatentsonline.com/result.html?srch=xprtsrch&jp=on&date_range=all&stemming=on&sort=relevance&query_txt=in%2Fberugasemu+or+in%2F%E3%83%99%E3%83%AB%E3%82%AC%E3%82%BB%E3%83%A0&search=Search
 * (my first name is so unique I do not need the last name to find them)
 * sorry to bother here and please continue the great work. Best All4dz (talk) 01:47, 13 December 2022 (UTC)
 * I can add non-US filings provided the source is reliable, reputable, enables search quality at least on par with the USPTO (which is by no means perfect), and does not result in double-counting. I don't know much about FPO, but it at least appears to offer better search capability than Google Patents. There might be a few issues with your link though.
 * Correct me if I am wrong because I might be, but the search does not appear to only include issued / granted utility patents. We can't have things like patent applications nor design, plant, etc. patents. Another issue is some JP patents seem to overlap with US patents (it is common for a patent to be applied for in multiple countries), which would count these patents twice. Is there a way for the query to only include issued, to only include granted, and to only include patents that were not also granted in the US? Keithrwalker (talk) 22:24, 13 December 2022 (UTC)
 * Thank you very for the fast reply.
 * I will look into and I am in line with you as far as double counting and granted patents vs applications and utility patents.
 * So I will search it closely and get back. However, many of them are issued in japan and those are from my early time before I came to the US.
 * Thank you again and thank you for the great work. All4dz (talk) 18:23, 14 December 2022 (UTC)

Promotion, conflict of interest and insertion of original research
If Rankin is notable, somebody without his obvious conflict of interest will need to write an article about him. Then, and only then, would he be added to the article. Don't encourage autobiography in Wikipedia, which is just an invitation for promotion and spamming. -- Orange Mike &#124;  Talk  10:34, 25 July 2019 (UTC)

Might be 2 inventors under same name
hello Keithrwalker Thank you for keeping this page updated. The inventor Gary W Grube, i believe there at least 2 inventors under the same exact name ( I know one of them). Unfortunately what makes it more confusing they both worked for ibm at a certain time. They are in different field but the only difference i could find is one of them use Illinois IL as inventor state residence. So it is possible to filter this case by added inventor state maybe. Just wanted to let you know. All4dz (talk) 12:57, 20 June 2020 (UTC)

Thank you, All4dz. I will look into it when I get some time. There isn't a good way to filter on state because if I query on ANDNOT IS/IL, it will rule out all patents that the prolific Gary worked on that have a co-inventor listed as IL. This only works in a few cases. But this will at least let me manually find these and hopefully find a way to correct the reference. I appreciate your help. --Keithrwalker (talk) 21:36, 20 June 2020 (UTC)

Thank you Keithrwalker I believe the one that should be in the list in this case is the one residing in IL so it is maybe simpler as to add AND IS/IL just guessing.... thank you again All4dz (talk) 14:09, 23 June 2020 (UTC)

Thanks for the correction. I misunderstood the scenario. Yes, the Gary Grube who qualifies is indeed the one with IS/IL. I checked all titles of both sets (with AND IS/IL and with ANDNOT IS/IL), and could find no anomalies, which was surprising. I updated my spreadsheet and the correction will go out in tonight's regular weekly update. Keithrwalker (talk) 21:28, 23 June 2020 (UTC)

Thank you again for your updates. All4dz (talk) 05:40, 24 June 2020 (UTC)

Request to add 2 inventors with 200+ patents
Hello Keithrwalker, Thank you very much for your time and effort in keeping this page up to date. May I recommend including the following 2 inventors with >= 200 utility patents from Micron Technology.

Troy Manning : https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&Query=APT%2F1+and+IN%2FManning-Troy%24&d=PTXT

Akira Goda : https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2FGoda-Akira%24

Thanks and wish you the best.Spacetravesty (talk) 07:58, 22 June 2021 (UTC)

Thanks, Spacetravesty! Troy definitely qualifies and I'll add to the article later today. Akira Goda does not qualify because there appear to be two inventors with the same name: one inventing in Japan for Toshiba and the other in USA for Micron and Intel. Sometimes a change in company and residence means the inventor moved jobs and countries, but in this case there is overlap of at least five years among filing dates. That could be explained if overlap were months apart or if we were looking at issuance dates that can be many years after an inventor left. Highly unlikely for such a long overlap among filing dates. Akira has 158 patents and I'll add to the Talk page to monitor. This is the query: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2FGoda-Akira+andnot+an%2FToshiba

Spacetravesty (talk) 22:52, 22 June 2021 (UTC) Thank you very muchKeithrwalker!, I very much appreciate your prompt response and including Troy. I triple checked the Japan submissions with Akira. All the submissions in Japan and USA are from him only. After Akira moved to USA, Akira's previous employer in Japan continued to file the branch patents from the original patent he wrote in Japan (dating back to 5 years). This explains the 5 years over-lap. Could you please let me know if you need more clarifications and I will try to furnish the details with you. Best Regards..

Thanks for the follow-up! I added Akira too. Both are now on the article. Although unusual, this can certainly happen. A company that takes so long to file may end up being beaten to some patents by their competitors! ;) If anyone challenges Akira's addition, they can compare signatures in USPTO's PAIR database. Sorry it didn't occur to me to check. Keithrwalker (talk) 00:12, 23 June 2021 (UTC)

Spacetravesty (talk) 02:05, 23 June 2021 (UTC) Thanks again Keithrwalker!, I very much appreciate your help. I just realized there is one more inventor that I know of with 200+ patents from Micron. Could you please also Yingda Dong. I am including the query for quick reference. My apologies for the multiple requests. Thanks in advance. https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&Query=apt%2F1+and+in%2FDong-Yingda%24&d=PTXT

Thanks, Suliu1! I added you to the article. I changed the ref to filter on company rather than city because that is more common and tends to be more accurate based on how USPTO search works (count was identical in your case). If you will change companies some day and continue to invent or if IBM transfers assignment for any of yours, we may have to change to cities or expand the company filter. You are welcome to update the article if you find it is ever missing any patents. Keithrwalker (talk) 04:11, 1 July 2021 (UTC)

please verify, Su Liu, 306 patents

 * Your ref includes other inventors besides the Su Liu who is listed as an IBMer. Su Liu at present seems to have 297. Below is the ref I am using. If you change the last "and" to an "andnot" you can see if this ref is omitting any that belong to this Su Liu. https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&d=PTXT&Query=apt%2F1+and+in%2FLiu-Su+and+an%2FBusiness

Possible addition of Shipeng Li, with 203 issued US patents
Thanks for keeping the list updated. I would like to suggest to add Shipeng Li to the list. He has now 203 issued US utility patents (most of them are done with Microsoft and Sarnoff). He is now with Chinese University of Hong Kong (Shenzhen). Thanks!

Thank you! Added to the article. Some notes: 1) I found 202 patents. If you change the ref's "and an/" to "andnot an/" you can look through the ones I don't think are this Shipeng Li's. Let me know if I missed any. 2) Although Shipeng is now in Shenzhen, Residence will be listed as USA as long as the most recent patent issuance has USA as Shipeng's residence. If Shipeng receives any patents with the Chinese University of Hong Kong, please update the country and ref in the article or let me know here and I'll do it. Keithrwalker (talk) 15:29, 5 July 2021 (UTC)

Missing Michael Ellis
Hey Keith, your list is missing my name. I'm not interested in self-promotion, but for accuracy you can add me. The search is complicated, as my name is fairly common, and the list of assignees is complicated and not updated in many cases after various corporate actions. By my count, I have 396 issued U.S. utility patents, and a significant number of patents in other countries that roughly correspond with the U.S. patents. Easiest is to filter based on my city of Boulder CO, but I can't guarantee there isn't another Michael Ellis with issued patents here. Silleekim (talk) 17:00, 28 July 2022 (UTC)

Thanks for letting me know, Silleekim. Congrats on your patent achievements! I'll check it out, see if I can find a good ref, and get you added to the article in the next Tuesday update. Yes, it can be challenging finding a good ref that excludes inventors with the same name. For example, I assume you aren't the Michael Ellis who co-invented "Substituted bicyclic compounds as bromodomain inhibitors." ;) --Keithrwalker (talk) 18:05, 29 July 2022 (UTC)

 * Thanks. Yes those are mine. Looks like you figured out all the various misspellings of Boulder as well as some with and some without the middle initial. I'm impressed. Presumably you don't include non-U.S. patents if they are based on the same original filing, even if the claims aren't an exact match. Is that correct? Silleekim (talk) 00:42, 3 August 2022 (UTC)
 * Yes, that is correct. Non-U.S. patents that were not also patented in the U.S. qualify and should be included, but I don't because I haven't found a source that would allow me to do that. Espacenet should be that source, but there were issues with its search engine (e.g., no ability to control wildcarding which spanned across multiple inventors!), and at one point they began blocking too many searches in a short time even when manually done, which is a show-stopper for an article of this size. When looking at it just now, it appears they have improved their search feature set, but a search on my name is missing ~100 that USPTO includes, and also many missing for other inventors I checked. Maybe there is some interfering default filter. Keithrwalker (talk) 19:54, 3 August 2022 (UTC)

New Inventor at 200 US utility Patents
Hi Keithrwalker, I just passed 200 utility patents a few weeks ago. I'm not sure how to provide you with a link, but on the US patent office you can search by: ((Chris or Christopher) near1 Jones).inv. and (Halliburton or Caleb).as. - Christopher Jones 135.26.79.51 (talk) 20:36, 6 April 2023 (UTC)


 * Thanks for letting me know, and congrats on your many achievements! I'll add you to the article's Talk page for inventors to watch when I next update that list. The article used to list anyone with over 200, but I had to change it to a top 100 format. Currently the 100th has 605. Even if you (like me) never make it to the top 100, it will still be good to have a USPTO URL that you can include in social media, CV / resume, email signature, etc. Keithrwalker (talk) 19:34, 7 April 2023 (UTC)
