Leslie D. Ware is a Dallas based lawyer specializing in patent management and licensing.

I have over 30 years of experience with patent prosecution including patent interferences.

Patent interferences can be identified early in prosecution when reviewing cited references if the reviewer is trained to recognize interfering subject matter. Once identified, an interference proceeding can be focused on the right issues or avoided.
