Lodsys Patents Under Attack as Legal Challenge to Their Validity Commences

FOSS Patents reports that Lodsys, the company that has begun filing lawsuits against App Store developers for implementing in app purchases and upgrade links, now finds itself on the receiving end of legal action. According to the report, a Michigan firm has filed a request for declaratory judgment regarding the validity of the four patents Lodsys is using in its own lawsuits. While a declaratory judgment against Lodsys would not automatically invalidate the firm's patent claims, it would set the legal framework for further challenges and negotiations both in and out of court.

Yesterday, the aforementioned Michigan company -- ForeSee Results, Inc. -- filed a proactive declaratory judgment action against all four Lodsys patents. In that complaint, ForeSee Results Inc. said that Lodsys had "threatened assertion" of one or more of its four patents against ForeSee's customers. Foresee names three examples of customers that received letters from Lodsys:

- Adidas (I have published that assertion letter on Scribd so you can take a look at it; it includes a claim chart that looks similar as the ones that many app developers received, though it relates to a different patent)

- Best Buy

- WE Energies

The report notes that the move is a preemptive strike by ForeSee Results, as its initial filing in Illinois could allow it to have any future lawsuits filed against the named companies transferred there instead of being adjudicated in the patent holder-friendly courts of the Eastern District of Texas where Lodsys has been filing its suits so far. And while the legal challenge to Lodsys' patents does not directly include the App Store developers targeted by the firm, a win for ForeSee Results could help bolster the developers' cases should a verdict come soon enough.
