Although, the length of utility and plant patent protection (patent term) was previously seventeen years from the date of patent grant, utility and plant patents filed after June 8, 1995 now have a patent term of up to twenty years from the date of filing of the earliest related patent application. Utility and plant patents which were applied for prior to June 8, 1995, and which were or will be in force after June 8, 1995, now have a patent term of seventeen years from the date of patent grant or twenty years from the date of filing of the earliest related patent application, whichever is longer. Utility patents are subject to the payment of periodic maintenance fees to keep the patent in force. Patent terms can be extended under some specific circumstances. See the U.S. Code Title 35 - Patents for a full description of patent laws.

When approached with this legal assertion, as a patent counselor for your client, you need insights to help you define and determine your defense. No, I am not: A patent is defined by its language, and many times, proper preparation for a Markman Hearing, or Claim Construction Hearing, can determine the summary judgment. If you are accused of infringing on a claim, you want to find ways to minimize the scope of the claim [on the other hand, if you are accusing, you want to broaden a claim's scope]. With IP Street, you can scrutinize a claim in various ways. Your patent is invalid: Since the USPTO granted the patent, the presumption is that all of its claims are valid. Anyone can challenge the validity of a patent (request re-examination) whether or not an infringement injunction has been made. [Normally, when the USPTO learns of an infringement lawsuit, out of due diligence, they open a re-examination case.] The quickest path to invalidate a patent is to identify prior art.
Executives need vision to convert patented R&D into a profit center. Consider EMI, a london company that produces music (a music label company). In their Central Research Laboratories in Hayes, Godfrey Hounsfield had an idea to integrate X-ray slices to create a 3-D image (originally known as an EMI scan), today know as a CT or CAT scan. Godfrey was awared a Nobel Prize for his work, and later knighted. The idea came to him while picnicking in the park; however, the senior executives realized this was no picnic. They leveraged the technology (foundation patent #3,778,614), securing over 120 of the first 450 patents in this space. The legacy competitors (General Electric, Philips, Siemens) were playing catch-up with this innovator. Few executives would be brave enough to execute such a divergent business strategy.
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.
