Power of Patents
No prior relationship between the patent owner and infringer is required
Independent design not a defense
Ignorance of the patent not a defense
Even the infringerĘs secret work prior to the patent is no defense
Notes:
Patents are one of the strongest property interests we have. Note that no prior relationship between patentee (the one who has the patent) and infringer (the one doing the making using or selling).
Copying is not required.--Independent creation is not a defense
Ignorance of the patent is not a defense
Even the infringerĘs secret work prior to the patentee getting the patent is not a defense. So patent it or you could lose it!
