Have Google’s spam filtering tools ever been accused of infringing a patent?

Yes. Google’s spam filtering tools have been accused of infringing a patent in at least two different lawsuits.

Interval Licensing LLC v. Google Inc., 2-11-cv-00711 (WAWD)
InNova v. 3Com Corporation et al., 2-10-cv-00251 (TXED)

While the Interval Licensing case focuses on Google’s Gmail spam filter, the InNova case includes Postini, Gmail, and “software and/or hardware used to filter e-mail sent to the domain ‘’”

Today’s question provides a great example of how Docket Navigator may be used to search for cases that involve particular parties and accused products or services. Check out today’s video to see how we did the search.
