If you haven't heard about Lodsys by now, I can guarantee you that you have heard about someone that Lodsys is suing for patent infringement.
After suing several large companies including: Brother, Canon, HP, Hulu, Lenovo, Lexmark, Motorola Mobility, Novell, Samsung, and Trend Micro in February and seven little app developers at the end of May, Lodsys filed a new complaint recently, with the U.S. District Court for the Eastern District of Texas against another ten companies.
About what you ask? All about anyone potentially using: online help, subscription renewals, in-app purchasing, and interactive online advertisements. Lodsys has been defending four patents that they claim are being infringed upon. Apple which has signed a licensing agreement with Lodsys will try to intervene in Lodsys lawsuit against the app developers that they are working with claiming that the licensing agreement should protect their app developers as well.
Bounty on Lodsys Patents
According to CNET News - Article One Partners, a business that crowds-sources intellectual property research, has launched three new studies into patents held by Lodsys (1,2,3). Each offers a reward or bounty to the party that finds prior art, or examples of pre-existing technologies or other IP that could be used as evidence to invalidate one or more of Lodsys' patents.
