If the complexities of legalities seems simple, you may want to consider becoming a patent agent or patent attorney. If you are a do-it-yourselfer (DIY), you may want to get David Pressman's book "Patent it Yourself" or David Hitchcock's book "Patent Searching Made Easy". If you are like the rest of us, this process does not seem simple. Sure it may cost some money to engage someone to guide you through this process, so you need to carefully consider your innovation in context of (1) is it patentable? and (2) is it a viable business opportunity? It may, however, be in your best interest to learn as much as you can about the system and then hire a competent patent attorney to get the job done. Just think what it would cost to great idea, poorly patented, which may ultimately cost you "like a bigillion dollars in lost royalties or something like that."
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.
Myopia is generally what happens when unprecedented opportunities are placed before them. Those in the know generally do better than those in the worry. Consider Cetus, a startup biotech with a focus on a liver drug. The FDA delayed the approval of the drug, and a major funding crisis ensued. Chiron offered to take over the liabilities contingent on the sale of two patents (# 4,683,202 and # 4,683,195) to a third party, Roche Molecule for $300M (in 1993). This sale was stalled because DuPont challenged the validity of the patents, based on the formal claims written by the inventor (not a patent attorney), Kary Mullis. In the end, the soap opera turned out well for the investors with weak constitutions. For $300M, they sold the two patents to Roche, turned the company over to Chiron, and walked away. Kary Mullis won the Nobel prize for his invention embedded in these two patents, known as polymerase chain reaction (PCR) which allows DNA to be cloned. Over 4000 patents in biotech cite these original two patents. In our estimation, $300M represents "pennies on the dollar" valuation of these patents. The shareholders got a payday, and left the game. Roche on the other hand is thriving based on its intangible assets. Let IPstreet.com assist you.
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.
A patent is a property right for an invention granted by a government to the inventor. A United States patent gives inventors the right "to exclude others" from making, using, offering for sale, or selling their invention throughout the United States or importing their invention into the United States. In exchange for this monopolistic protection, the inventor must publicly disclose the invention (the patent document) and must pay the United States Patent Office (USPTO.gov) to prosecute (application fees) and maintain (maintenance fees) the patent.
