Indie Devs Get Hit With Lawsuit Threats Over In-App Purchases

UPDATED.┬áDevelopers who offer in-app purchasing in their apps for iOS might want to check their mailboxes this morning, as apparently FedEx-delivered (s fdx) lawsuit threats are currently making the rounds. The threats accuse devs of patent infringement regarding Apple’s in-app purchase mechanism, but the patent holder appears to be targeting independent developers individually instead of going after Apple (s aapl) itself.

James Thomson of TLA Systems was the first to discuss the threat early Friday morning, as reported by Cult of Mac. Thomson was targeted by the patent holder because of in-app purchases available to users of pCalc, an iOS scientific calculator app. Thomson reports that though he hasn’t been sued yet, the patent holder wants him to license their tech, and gave him 21 days to comply.

Thomson isn’t alone, either. Patrick McCarron, who creates apps for MobileAge, also confirmed receiving the same notice via FedEx early Friday. McCarron’s offending app was a game, so it seems like the company behind this is casting a wide net. Neither Thomson nor McCarron has yet to reveal the name of the company targeting them, though McCarron did assert that it’s not MacroSolve, a company that has been very active recently in enforcing its mobile technology patents.

Apple has been contacted by both devs, and will likely move quickly to respond to these threats in order to prevent widespread concern among the developer community. As of yet, Apple has yet to comment officially on this development. We reached out for comment, but have yet to hear back.

This kind of suit could provide a dangerous precedent, if not quickly quashed. Google (s goog) and RIM (s rimm) recently introduced in-app purchasing, and presumably those systems would also be in violation of these patents. We’re working on discovering the source of the threats, and will update when more information becomes available.

UPDATE: The company behind the patent suit threats is apparently Lodsys, a patent holding firm which has held patent no. 7222078 (the one which is claimed to have been violated) since 2004. Lodsys cited the same patent, along with several others, when it filed suit against a number of major printer companies in early 2011, according to MacRumors.

Lodsys’ entire business consists of licensing the patents it holds, which is completely in keeping with the licensing demands developers have so far been receiving. If you feel like making your feelings about this latest round of threats known to Lodsys, you can contact the company directly via its official website.
