My fourth video about Provisional Applications is now up. You can view this at:

This video discusses problems with provisional applications like prosecution history estoppel, Patent unenforceability, and EPO scope issues.

The video also describes when Provisional Applications might be the best option. This can occur when you are getting close to a statutory bar and do not have enough time to file a non-provisional application. If this is the case a provisional may be better than gifting your idea to the public.

Also, some entities do prefer to file Provisional applications. They get around the problems associated with Provisional Applications by filing a 35 U.S.C. 112 paragraph 1 compliant specification and drawings as well as a complete set of claims.
