Michael E. Byczek, Attorney at Law
The most important element of a patent is the claims, which define exactly what is being patented. The claims determine what the patent protects. The application requires a written explanation and drawings, but the exact terminology used to write the claims is what matters the most.
Your patent must explain in clear and precise technical terms exactly what you invented. This determines whether your invention is new and if somebody else has violated your rights, just like a real estate boundary dispute. If nobody knows where the boundary is, how can anybody determine what is and what is not protected?
A standard application consists of under 20 total claims. Only three can be Independent form. A Dependent refers to an Independent.
The following 12 examples are from actual patents that the USPTO has granted.
