In a recent decision, the Patent Trial and Appeal Board (PTAB) issued mixed rulings in a series of patent challenges initiated by Intuit, the company behind TurboTax. The challenges were directed at a small software company that asserts it pioneered the concept of “co-browsing.” While Intuit succeeded in invalidating two out of the three patents in question, one patent was upheld by the PTAB. More details on this development are available through Law360.
