Software inventions are patentable within the U.S., and in many other important jurisdictions. Nevertheless, not all other countries permit broad protection for software innovation. Two with the much more essential patent offices, the European Patent Office (EPO) and also the Chinese State Intellectual Property Workplace (SIPO) restrict how software inventions might be protected. Nevertheless, many types of the software program can still be protected in China and Europe.
Europe
The EPO precludes patenting.
(a) Discoveries, scientific theories and mathematical methods;
(b) Aesthetic creations;
(c) Schemes, rules and techniques for performing psychological acts, playing games or doing company; and
(d) Programs for computers and presentations of info "Nevertheless, there’s an exception. Article 52(two) excludes "the patentability with the subject-matter or actions referred to therein only towards the extent to which a European patent application or European patent relates to this kind of subject-matter or actions as this kind of."
This clause produces an exception for certain kinds of software program innovations to become patentable topic matter in the EPO.
The EPOs patentable topic matter includes the technical or hardware associated elements of an invention, as opposed to functions, which are simply algorithms. This really is not an apparent distinction. Within the U.S., algorithmic components may be protected, if claimed correctly. In Europe, algorithms, this kind of as an accounting program that is executed on a common purpose computer isn’t patentable.
Nevertheless, software that does something to hardware is likely to become patentable. For example, software that controls communications among machines is more likely to be patentable topic matter. Similarly, software that accelerates graphic display functions is most likely patentable.
EPO patent applications are also structured differently from U.S. patent applications. The application should follow a problem/solution format. A technical issue is described and a solution, the invention, is then presented. This is in sharp contrast to US applications exactly where the issue description is frequently minimized so that it isn’t utilized against the applicant as prior art.
The claimed embodiments of the EPO application are directed towards the problem. EPO software program claims are organized as two-component claims, having a preamble that lists elements that are recognized within the art followed by a second part with the novel inventive components.
China
In China, software program, algorithms or computer games are not per se patentable subject matter. Software program inventions must resolve a technical problem and have physical functions. So like in Europe, your clever accounting or stock evaluation algorithms are not patentable subject matter.
However, software program with physical features such as accelerating information interchange or storing data much more effectively solve a technical issue, and so are likely to become patentable subject matter.
Even though Europe and China don’t assistance the protection of software inventions towards the exact same extent as the U.S., you are able to protect numerous types of software innovations in those jurisdictions.
