Someone is copying my product. Can my patent stop them?

It comes down to two things: whether their product falls within the scope of your patent, and whether your patent can survive an invalidity challenge. Put the patent number and what you know about their product in the form, and the lawyer will start from these two points.

What should I write in the form?

In brief: who the other side is, which patent or product is involved, what you received and when you received it. Do not send full confidential technical files. File upload is not available on this page.
