Patent Term
The term of a patent depends upon the laws of the country in which it is issued. In most jurisdictions, a patent term is 20 years from the earliest filing date of a non-provisional patent application. In the United States, a patent’s term may be lengthened in some cases by patent term adjustment, which compensates a patentee for administrative delays by the USPTO in excess of a patent applicant’s own delays during the prosecution process, or may be shortened if a patent is terminally disclaimed over an earlier filed, commonly owned patent. In addition, the term of a patent that covers a drug or biological product may also be eligible for patent term extension when FDA approval is granted, provided statutory and regulatory requirements are met. However, the extension shall not exceed five years and the resulting total effective patent term shall not exceed 14 years from the FDA approval. In the future, if and when our drug candidates receive approval by the FDA or other regulatory authorities, we expect to apply for patent term extensions on issued patents covering those drugs, depending upon the length of the clinical trials for each drug and other factors. In China, the amended PRC Patent Law provides for both patent term adjustment and patent term extension, similar to the United States. There can be no assurance that any of our pending patent applications will be issued or that we will benefit from any patent term extension.
Similar extensions as compensation for regulatory delays are available in certain foreign jurisdictions. The actual protection afforded by a patent varies on a claim by claim and country by country basis an depends upon many factors, including the type of patent, the scope of its coverage, the availability of any patent term extensions or adjustments, the availability of legal remedies in a particular country and the validity and enforceability of the patent.
