Patentability of mathematical modelling and simulation methods

Abstrakti

”Patentability” refers to conditions laid down by law on what can be patented and what cannot. In this
study, changes in the patentability of simulation methods are compared with the rapid development of
computational science since 1970’s. Although technological progress has caused computational simulation
and modelling methods to grow to an everyday tool of technology, these methods have traditionally been
excluded from patentability as “non-technical subject matter” or “abstract ideas”. We describe the changes
in patentability criteria in Europe and in the USA, and illustrate the development of patenting activity
during the last decade. Practisers should be aware of these changes, and investigate the possibilities they
might offer.
