Patents have a maximum life of 20 years and, therefore, a 20-year potential monopoly. Patents that are just beginning their life and which have longer to run on the their potential monopoly position understandably will have more value. It is rare that a patent nearing the end of its term will cause a great threat to its competitors. It is almost certain that they will have devised technologies or products of their own by then that will not interfere with the patent owners monopoly position. In addition, one has to take into consideration the potential business life of a patent, i.e., the duration, which a patent is likely to be economically useful, if other subsequent patents are providing better alternatives to it.
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.
