Dispute over name
In some markets, Panasonic has accused Pensonic of being a knockoff of former's through the similar brand name and affecting their market share, leading to lawsuits. Pensonic says that its the name was created by combining Penang and Sonic to mean the "sound of Penang".

In 2008, Panasonic won an injunction against Pensonic on Singapore. In Sri Lanka, Pensonic successfully won a judgement to register its trademark in January 2009 against opposition by Panasonic. The judgment observed that Pensonic was previously registered in Malaysia, Japan, and many other countries without the objection of Panasonic.
