Patent issues to consider:

8. Unless you file your U.S. patent application within one year after you first offer your invention for sale or publicly demonstrate the invention, you lose the right to obtain a patent. In most other countries, though, the right to obtain a patent is lost unless the application is filed no later than the date of first sale or publication.

10. If you threaten to sue a competitor for infringing your patents, the competitor can initiate a lawsuit against you seeking a "declaratory judgement" that your patent is invalid or not infringed. The competitor may thus potentially obtain a tactical advantage, for example by bringing the suit in a local or other more favorable court of its own choosing. But a non-threatening offer to license your patent to an infringing competitor will not generally support such a preemptive lawsuit.
