Building a strong base for IP protection will make it difficult for other people and companies to infringe upon protected rights. One way to secure intellectual property protection is to cover IP with various types of IP rights. Patent infringment is a serious threat for anyone interested in patenting an idea or interested in patenting an invention. Imagine that the IP of a particular U.S. company is a novel paintbrush. The company can obtain a utility patent in the United States covering the novel paintbrush. If the company has business in Europe, it might be wise to file a PCT as well. It might be beneficial to write a claim, also, for painting with the paintbrush. By doing so, the company would ensure that both people manufacturing the brush, and each small or large painting using the brush, would be guilty of infringement if they were not first granted a license to use the brush in any manner they saw fit. When the company holding the patent improves the tool, it can always file a new patent covering the improvement (continuation-in-part application). Additionally, a design patent might protect the design of the paintbrush. Finally, the company might have a unique name for the tool that could be trademarked. The patent search tools and resources provided at IPStreet.com, will help you better understand patent duration, how to protect from patent infringement and ways to connect to experienced patent lawyers.
In the U.S., the inventor has a "first to invent" claim which is different from other patenting organizations throughout the world who generally utilize "first to file." Debate over this issue, and which model best influences economic development is ongoing. Some are concerned that a change in patent rights may harm the small startup and benefit the incumbents with deeper pockets. You can read more about this topic.
There are three types of different patents (1) Utility Patents: Issued for the invention of a new and useful process, machine, manufacture, or composition of matter, or a new and useful improvement thereof, it generally permits its owner to exclude others from making, using, or selling the invention for a period of up to twenty years from the date of patent application filing ++, subject to the payment of maintenance fees. Approximately 90% of the patent documents issued by the USPTO in recent years have been utility patents, also referred to as "patents for invention." (2) Design Patents: Issued for a new, original, and ornamental design for an article of manufacture, it permits its owner to exclude others from making, using, or selling the design for a period of fourteen years from the date of patent grant. Design patents are not subject to the payment of maintenance fees. (3). Plant Patents: Issued for a new and distinct, invented or discovered asexually reproduced plant including cultivated sports, mutants, hybrids, and newly found seedlings, other than a tuber propagated plant or a plant found in an uncultivated state, it permits its owner to exclude others from making, using, or selling the plant for a period of up to twenty years from the date of patent application filing. Plant patents are not subject to the payment of maintenance fees.
Proper organization of a patent porfolio is essential to be prepared to properly navigate the IP landscape. One key issue is related to inventorship. Consider the Pfizer patent, patent # 5,760,06^, which is commonly known as the COX-2 inhibitor. Pfizer is currently in a $1B lawsuit because Searle, the original owner of the patent, failed to include a key inventor on the patent. Pfizer inherited this mess when they acquired Pharmacia, who had previously acquired Monsanto, who had previously acquired Searle. Ignorance is not a defensible excuse in patent litigation.
