A patent gives the patent holder the right to exclude others from making, using, offering to sell, selling, or importing into the United States the subject matter of the patent, during the term of the patent. A patent term is 20 years from the filing date. The United States Patent and Trademark Office (USPTO) determines whether a patent should be granted in a particular case. Once a patent is granted, it is up to the patent holder to enforce the patent rights against infringers.

U.S. Patents are enforceable only in the United States.

A patent attorney prosecutes a patent application before the USPTO in a process referred to as patent prosecution.



Utility Patents (Most Common): for discoveries of new and useful machines, composition of matter or any improvements thereto.

Design Patents: a design patent covers any new, original and ornamental design for an article of manufacture.A design patent protects only the appearance of the article and not structural or utilitarian features.

Plant Patents: a plant patent covers new varieties of asexually reproduced plants.

Novelty Search or Patentability Search: a novelty search is the most common type of patent search. Novelty searches are conducted when an inventor has an invention which he is interested in patenting, and wishes to determine if anyone has previously invented anything similar or identical. Typically, a patent attorney reviews the results of a novelty search and provides a patentability opinion as to whether or not the invention is patentable based on the results of the novelty search.

Clearance Searches: A Produce Clearance Search or Freedom to Operate Search identifies patents and published applications that may pose an infringement risk to your product or service. Additionally, expired patents that may indicate that your product or service is in the public domain are identified. The search scope may be limited to US patents and published applications, or extended to include foreign patent references depending on your needs.

Validity Search: identifies rior art references that may be used alone or in combination to contest the validity of the claims in a patent or patent application. Search results may include published applications and issued patents, both US and foreign, as well as non-patent literature such as scientific journals and papers. The results of a validity search can then be compared to the claims of a patent which is the subject of a validity analysis.

Patent Enforcement: Actions taken by a patentee against a party who is making, using, or offering for sale a product or method covered by a patent (patent infringement).


We will provide flat fee or capped fee quotes for most patent related services upon request and review of the scope of the services to be performed.
