What is a Patent Violation? According to Wikipedia a Patent Violation is the commission of a prohibited act with respect to a patented invention without permission from the patent holder. Permission may typically be granted in the form of a license. The definition of patent violation may vary by jurisdiction, but it typically includes using or selling the patented invention. In many countries, a use is required to be commercial (or to have a commercial purpose) to constitute a patent violation.
The scope of the patented invention or the extent of protection is defined in the claims of the granted patent. In other words, the terms of the claims inform the public of what is not allowed without the permission of the patent holder.
Patents are territorial, and infringement is only possible in a country where a patent is in force. The scope of protection may also vary from country to country, because the patent is examined by patent office in each country or region and may have some difference of patent ability, so that a granted patent has not worldwide enforceability.
