It is interesting to note that there is NOT a single company from China & India. I looked briefly at the methodology applied in the Thomson Reuters study and yet to review the detailed report. I suppose I will have many issues to pick on! The report does mention the fact that even though China filed many patent applications, it did not make it to the list third year in a row... perhaps Chinese companies under consideration did not 'influence' enough globally!
@Martin: test companies are usually taken for granted... the test equipments are amazing pieces of technology, whether one is using a 40-gig PHY layer tester, traffic generators. etc.
I believe Adafruit does in fact patent their stuff, but they also have an open license for use. I'm not sure of the details, but I've heard this is so they can stop big companies from patenting their stuff and closing it to the public.
...after all their measurement is solely based on some "patent related metrics" they're not very forthcoming in talking about. I'm sure that outfits and organizations like Adafruit, Arduino, Parallax, Raspberry (Pi) and others will be interested to know that they're not even being considered to be involved in "innovation". Outrageous!
