Patent Guide

A patent is an intellectual property right granted to inventors by a country’s government for a limited period to exclude others from making, using, offering for sale, selling or importing the invention.

There are three main types of patents – utility, design, and plant. A utility patent is granted for a new and useful process, machine, article of manufacture, or composition of matters, or any new useful improvement thereof. A design patent is granted for a new, original, and ornamental design for an article of manufacture. A plant patent is granted for new, asexually reproduced plant varieties.

Patent Search

To be patentable, the invention must be statutory, novel, useful, and nonobvious. A thorough patent search helps assess the novelty and non-obviousness of your invention and allows you to make a more informed decision on whether to pursue your patent application or not. It also helps you to discover which companies might be interested in licensing your invention.

  • Seven Step Strategy – A step-by-step strategy for a preliminary patent search.
  • Patent Classification – The page to access the Cooperative Patent Classification (CPC) System and the U. S. Patent Classification (USPC) System. You can browse or search them by classification symbol or keyword.

A fire at the USPTO in 1836 destroyed these unnumbered patents. Some of them were reconstructed based on the inventors’ records, reference books, and the patent examiner’s memory, and the letter X was added to each serial number.
  • Index of Patents – HathiTrust Digital Library contains the collection of the historical patent indexes – Annual Report of the Commissioner of Patents (1842-1921) and Index of Patents Issued from the United States Patent Office (1920-1974).

Effective February 2, 1971, the Official Gazette was separated into two parts, the Patent Official Gazette and the Trademark Official Gazette.

Trademark Guide

A trademark is any word, name, symbol or design, or any combination of these, used in commerce to identify and distinguish the goods or services of one manufacturer or seller from those of another.

There are four main categories of trademarks – fanciful or arbitrary, suggestive, descriptive, or generic. The category your mark falls into significantly impacts both its registrability and your ability to enforce your exclusive rights in that mark.
