When you apply for a U.S. patent, it's because you're looking for the valuable legal protection it can provide. You've dedicated significant time and effort in perfecting your invention, and naturally, you want to be the sole provider of it. However, it's crucial to understand that although the United States Patent and Trademark Office (USPTO) is responsible for granting patents, they don't actively monitor or enforce your patent rights against potential infringers. This responsibility solely rests on you as the patent owner. It's essential to be proactive in protecting your rights and taking appropriate legal action if infringement occurs.
