To point 4, Nokia USED to make phones, which means that they are more than just a patent troll.There is a better summary of this at Bloomberg ... https://www.bloomberg.com/news/arti...-over-alleged-patent-infringement-in-products
1. Apple and Nokia had a contract that both cross licenced patents which expired.
2. Nokia doesn't make phones any more so the patents Apple owns are useless to Nokia, so Nokia wants to be paid in money instead in of Apple gift cards or cross licencing of Apple's patents.
3. Nokia won a court case last week against Apple. Jury said Apple was using Nokia's patents.
4. Apple is calling Nokia a patent troll now cause they don't make phones.
5. The patents in the story say they are use in the iPhone for video over cell connection and for Siri. Those don't sound like FRAND patents.
That being said, here is how Patents are supposed to work:
- Company A invents something really cool and useful through research and development.
- Company A applies for a patent by submitting drawings and everything else that would be needed to build on the idea in the future.
- The patent is approved
- The patent prevents others from using the work or creating derivatives without a licensing deal with Company A for a limited amount of time to allow Company A time to recoup their costs and make a nice profit.
- Once the limited amount of time is up, the original design becomes open source allowing other companies to freely use the concept and build new products upon it.
- So Company B adds some cool new functionality and then they can patent that new functionality and the process starts over.
Many question if the patent process still works in today's fast paced tech world and the reality is if it was run as originally intended is that while you might need to adjust the amount of time in step 4 accordingly, it would still work.
