Lodsys, LLC was a patent company located in Marshall, Texas that brought patent infringement lawsuits against a variety of companies in the US. Numerous app development enterprises have accused them of " patent trolling", referring to the fact that they have sued many developers over alleged usage of Lodsys' patents, pressuring a lot of them to settle rather than face the time and expense of fighting the lawsuit. On May 13, 2011, it was reported that they had demanded that a number of iOS application developers obtain licenses from them. Apple has written to Lodsys stating that Apple's licenses protect its app developers. However, Lodsys has decided to press on with their lawsuit and has sent a detailed legal response to Apple. According to the company website, Lodsys states that it is not a corporate subsidiary of patent holding company Intellectual Ventures, contrary to speculation from media sources.
