I'm building a (for-pay) web/mobile app that will generate PDF reports for customers. Do I need to pay someone a royalty? Who? How much and what are the terms?

Surprisingly, the best info I was able to find was from the PDF wikipedia page where it simply lists PDF as an "Open" format. But no mention of royalties, etc.


Adobe grants every individual and organization in the world the royalty-free right, under all Essential Claims that Adobe owns, to make, have made, use, sell, import and distribute Compliant Implementations. If a licensee brings (or participates directly or indirectly in the bringing of) a lawsuit or similar action against any other party claiming that a Compliant Implementation infringes an Essential Claim, Adobe may revoke the rights granted above to such licensee. Upon such revocation, such rights will be deemed to have never been granted.

  • So, in layman terms, "it is free, but if you piss me you are going to thoroughly regret it"? – Davidmh Dec 10 '15 at 9:29
