Practice Areas / Patent Law

The Patent attorneys of Pittsburgh based Ference & Associates appear as counsel on over 900 issued US patents and can assist you with all aspects of the patent process.

A patent is a form of legal protection for intellectual property. It consists of a set of exclusive rights granted by a sovereign state to an inventor or their assignee for a limited period of time in exchange for the public disclosure of an invention.

The procedures for granting patents vary widely between countries according to national laws and international agreements. Typically, however, a patent application must include one or more claims defining the invention which meet the relevant patentability requirements such as novelty and non-obviousness. In most countries, the exclusive right granted to a patentee is the right to prevent others from making, using, selling, or distributing the patented invention without permission.

What can be patented and the length of protection differ in many parts of the world. For example many computer programs and business methods are not patentable in
many countries, but are typically afforded protection in the United States.
