It seems that TechCrunch is part of the lawsuit because they have either written about Loopt in the past or Loopt is a sponsor/advertiser on TechCrunch.
Here’s an excerpt from the complaint that was filed by the lawyers of Earthcomber against Loopt and TechCrunch:
- Plaintiff EARTHCOMBER is the owner of United States Patent No. 7,071,842 (the ‘842 Patent’).
- Defendant LOOPT has infringed and continues to infringe the ‘842 Patent by making, using, selling and/or offering for sale products and/or methods covered by one or more claims of the ‘842 Patent without Plaintiff EARTHCOMBER’s authorization in violation of 35 U.S.C. § 271(a).
- Defendant TECHCRUNCH has actively induced and contributed to the infringement of the ‘842 patent in violation of 35 U.S.C. § 271(b) and (c).
I am sure Arrington would soon publish the ‘threat letter’ and his take on on TechCrunch but until then, you can download a full copy of the complaint here.
