1 in 8 Patents Has a Flaw You Only Find When You Try to Enforce It
Patent examiners check whether an invention is new. Whether the patent will hold up when its owner tries to use it is a different question, and the first time it gets asked is usually in litigation. We analyzed all 564,109 independent claims granted over eleven months, each judged against the litigated claims of its own technology area: one new patent in eight carries a verified flag, and flag rates between large filers run 28-fold apart.
