TECH CRUNCH - May 6 - Pair picked up a $4.2M seed round, money the founders said would be used to expand its mobile development and design teams. Now it looks like some of those funds might also need to go to legal bills. Tenthbit, the developer behind Pair, is getting sued by pair Networks, a hosting and domain registration company for trademark infringement. Tenthbit, meanwhile, has also sued pair Networks, to try to prevent the other suit from going ahead. Pair Networks is asking for an injunction on Pair the app, as well as “other relief as this Court deems appropriate.” Tenthbit argues the two do not compete directly, and would therefore not result in any brand confusion. Pair, the app, has seen ~220K downloads since it went live in the app store a month ago. Pair Networks says that it has been policing for the use of its name by Internet-related companies for years now, and cites three different examples in its complaint where courts have ruled in its favor in other trademark infringement cases. Pair Networks claims that its reputation is being damaged because Pair the app is associated with “explicit adult activity” like “sexting.” Pair Networks is asking to get all the profits that Tenthbit will have made from Pair app.
