Google loses invalidation call on traffic information patent


2019-04-10 15:30:43


Google has lost a court battle with an inventor after it called for invalidation of a patent related to a traffic information system.

The search engine giant alleged that a US patent (6,233,518) assigned to Ji-Soo Lee was invalid in two of its claims (45 and 46) and filed an inter partes review petition.

The Patent Trial and Appeal Board (PTAB) opted to review both claims, but only on one of the five grounds Google raised in its petition.

In its final written decision, the board held that Google failed to establish that claims 45 and 46 are unpatentable.

Upon appeal to the US Court of Appeals for the Federal Circuit, Google again was rebuffed after it affirmed the PTAB’s ruling.

The Court of Appeals remanded the case back to the PTAB for it to consider whether claims 45 and 46 are unpatentable based on the four non instituted grounds raised by Google.

The court awarded costs to Lee.
