In an amended SEC filing ahead of its IPO, Reddit warned potential investors that "...on March 18, 2024, Nokia Technologies sent us a letter indicating they believed that Reddit infringes certain of their patents. We will evaluate their claims." Nokia, of course, leaned into, ahem, patent licensing and networking equipment as its business many years ago, and reminded people of it with last year’s logo redesign. Companies paying Nokia licensing fees include HTC, Apple, and more recently, Oppo.
If you’re enforcing a patent that would have been come up with other people in the same field, then the patent is invalid, many of us would consider going after people with an invalid patent – patent trolling.
Patents are meant for UNIQUE ideas and things that nobody else would have come up with on their own. But increasingly they’re being used for obvious ideas that thousands of other people also have around the same time, to lock out competition.
