Patent Troll = Patent Cockroach (In China)

In a report on, Mark McCarthy describes the potential for major NPE activity in China, particularly due to the China’s laws regarding utility patents:

“The threshold of inventiveness is lower for utility model patents.  As compared to prior art, an invention patent has “prominent substantive features and represents a notable progress;” while a utility model patent merely has “substantive features and represents progress.” As a result it is more difficult to invalidate a questionable utility model patent. And there is no mandatory examination upon filing an infringement action.

The utility models are issued without substantive examination typically in under 6 months (3 months is the target) Utility models are 20% cheaper than invention patents to obtain.

Because of these attractive features utility model patents are growing quickly.  Most of these are owned by Chinese individuals.”

And, note this ominous part: “The situation is ripe for abuse.  Since 2008, well-known non-practicing entities have begun to establish a presence in China. It is only a matter of time before the patent troll problem burst out there and by then it will be too late to prevent the damage these.”
