I got it. Your concern makes sense. > My advice is to write up a patent grant that allows all to use the > relevant patents royalty-free with a no-lawsuit covenant. I.e., make > only defensive use of your patents. How can one make defensive use of his patent if he allows everyone to use it royalty-free? Can he use his patent for cross-licensing negotiation if some commercial database vendor accuses his company that PostgreSQL unintentionally infringes that vendor's patent?
