US provisional patents & patent strategy – why wouldn't you
Dennis Crouch over at Patently’O has just posted a note on some research he has done on the use of provisional patent applications by applicants in various jurisdictions, and by various big-name applicants in the US.
What’s astounding to me is that there is less than 100% uptake of the US provisional – the main reason being that it gives an extra 12 months ‘grace period’ under 35 USC 102(b) [that’s before you filed the application] in one of the world’s largest markets.
Why wouldn’t you file a US provisional? Let me know what you think I’m missing.
