Patent Listserv

This listserv is a forum for member companies that have received letters from patent owners alleging infringement and/or had legal complaints filed against them by patent owners. Unfortunately, “patent trolls” are a growing menace to the printing industry. Currently there are a number of trolls asserting patent rights against printers. [A troll is a company that purchases patents for the sole purpose of intimidating firms into paying for a license, quite different from patent owners that use their patents.] 

The way a listserv works is you will receive an email whenever another listserv member sends a question or comment on the topic. Here are some of the ways you can use this listserv:

  • Find out if other companies have been approached by the same patent troll
  • Share the content of demand letters and associated licensing fees
  • Ask for advice on how other companies have responded to a patent troll
  • Share and solicit defense strategies
  • Seek printers interested in forming joint defense group

If you feel uncomfortable asking a question directly, click here and the question will be posted anonymously.
