regression

Here are the results of a regression comparison of all software litigation and all software patenting activity since 2000. The results show correlation which could be described as somewhere between moderate and strong. The resulting Peason’s R value for this study is 0.5193. The purpose of doing this regression study is to prove some correlation between litigation and R&D expenditure. Patent grants issued are not a direct measure of R&D expenditure, because patents costs different amounts to produce in different industries. However, these are all software-related classes, and so correlation between grants issued and R&D expenditure should be stronger than when measuring all UPC classes for the whole USPTO.
