Law - Information Presentation

PCT rules stipulate that no International Searching Authority (ISA) is required to search and no International Preliminary Examining Authority (IPEA) is required to examine an international application if its subject matter is "mere presentations of information" (PCT Rule 39.1 and PCT Rule 67.1) National and regional patent offices prohibit the patenting of such subject matter. For example, in the U.S. a novel method (an alleged "process") is unpatentable if it does not have utility within the technological arts, [i.e., if the process merely manipulates "nonfunctional descriptive material" (e.g., numbers, compilations of facts or data, abstract ideas or concepts)]. EPO rules likewise deny patentability to "any representation of information characterized solely by the content of the information" but note that "the arrangement or manner of representation, as distinguished from the information content, may well constitute a patentable technical feature."

Because one of the primary advantages of filing an international application is that a thorough search and preliminary examination will provide some assurance that national applications will be successful, an applicant may be well advised not to file an international applicant if the subject matter falls into the above areas. If the USPTO ISA or IPEA conducts the international search or preliminary examination, however, it will search and examine all subject matter searched and examined in U.S. national patent applications.

The position of the USPTO on this issue (in the role of the ISA or IPEA) is described in the following section(s) of the Manual of Patent Examining Procedure (MPEP):

MPEP 1843 - The International Search
MPEP 1849 - Subject Matter Excluded from International Search
MPEP 1874 - Determination if International Preliminary Examination is Required or Possible
