Types of Patents

Types of patents

Utility Patent

Best known: The best-known patent application is the Utility Patent which protects something with a function like tools, games, toys, electronics, vehicle parts, and high and low-tech devices.

Lesser known: “Better mousetraps” aside , there is a lucrative trend toward patenting less obvious items. Our registered patent attorney, Michael L. Greenberg, has filed utility patent applications relating to online business methods, stock market prediction methods, traditional business methods, and certain types of software.



Design Patent
Look, not function: A Design Patent  protects the look and feel of an item but not its function.

Plant Patent
Powerful tool: Researchers expend time and money producing new or original varieties of plants via asexual reproduction. This is a specialty patent that can become a powerful tool in the right situation.



Patent Cooperation Treaty (PCT) Application

International scope: Most American, Asian, and European countries are signatories of the Patent Cooperation Treaty (PCT), which provides patent applicants with a priority date in every country that is part of the treaty. Aside from extending this protection beyond the United States, the PCT is important because it often considers the application more quickly than the United States Patent and Trade Office (USPTO).

Greenberg & Lieberman clients range from solo inventors to corporations around the world in determining whether their ideas have become patentable inventions.

Our business is your business

Filing a patent application is an important and potentially lucrative step in the life of an inventor and business. One CEO threw a “patent-pending party” for his staff after their stock method application was filed. Another inventor promptly sold his construction system idea for millions of dollars only a week after filing his application. Many other inventors have begun seeking investors after filing, arranging meetings and launching marketing campaigns. In contrast some inventors realize the daunting task ahead and quietly pursue their business plans.

What is done: Whether retained in the very beginning or later in the patent process, ,we assure our clients of personalized service and confidential representation. After consulting with you about the nature of your invention, our registered patent attorney, Michael L. Greenberg writes the application, arranges drawings, files the application, and monitors its progress through the government bureaucracy.

After filing: We continue to monitor the status of each application we file, including personal visits to the patent and trademark office if necessary or requested. The patent office rarely grants an application exactly as requested and will issue office actions which are not included in the cost of writing and filing the original application. We will continue to work with clients on post filing issues including trademarks, infringement issues, incorporations, contracts, licensing, assignments and virtually all intellectual property legal services.

Policing your intellectual property:  Failure to protect your Intellectual Property (IP) is implied permission to potential infringers. Patent, trademark and copyright infringement is not a criminal matter, so it is up to you and us to monitor the use of your IP, to demand any infringers cease and desist their activities, and, if necessary, file lawsuits to make them stop.
