Hello, I'm Dwpaul. I noticed that you made a change to an article, VIN etching, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. ''a) Merely including a patent number is not verifiable evidence of the existence of a patent. See WP:CITE; also see WP:PATENTS.  Please do not reintroduce without one or more reliable citations.  b) The fact that someone was awarded a patent doesn't mean that they invented something. One "fact" does not necessarily imply the other. c) If this information was properly introduced (with citations), it would go in a new section called History, not in the lede of the article. It is not useful info to understand what "VIN etching" is nor how/why it is used, only (perhaps) how it came to be.''   Dwpaul   Talk   18:58, 11 May 2014 (UTC)
 * Also, as De Rossett himself makes clear in the preamble to his patent, he did not claim to have invented VIN number etching. In his description, he describes at least five different methods of doing so that predate his claim. His patent application proposes that he invented improved methods of VIN number etching, with very specific characteristics and qualities far too detailed to appear in (and irrelevant to) this article.
