Oliver Reichenstein in an interview with Dylan Love for Business Insider makes an interesting statement about patents:
While feel that Reading Time should be a common standard for everybody (other text editors and Websites started using it now as an indicator of text volume), we have a patent pending for Focus Mode. Some people criticized us for that. But we don’t make the rules of the industry. We follow them. Dealing with copycats is not all sunshine and rainbows. And if even bigger companies start copying us (the latest version MS Word now suddenly has a blue focus optimized cursor, just like Writer), we better have something to prove that this was our idea and not Microsoft’s or Apple’s.
I had no clue Word adopted the blue cursor, that’s pretty lame.
