Lodsys is now claiming that its patents cover cross-promotional links in apps, not just in-app purchases, according to one developer. The creator of iFighter 1945, EpicForce, remarks that several weeks ago, it received a letter stating that a "Get Full Version" link in the game violates a Lodsys patent. "The 'Get Full Version' link is actually for the purchase of Super Laser: The Alien Fighter," EpicForce writes. "This is just a 'cross promotion' and I think almost every developer is doing it. It's neither an In-App purchase nor a 'Lite to Full' conversion."
