A zig-zag path to victory in a landmark patent infringement case
FORTUNE — On Tuesday, a U.S. district court in San Jose, Calif., granted Apple’s AAPL request for a preliminary injunction against Samsung’s Galaxy Tab 10.1 — the tablet computer that most closely resembles Apple’s iPad.
“Although Samsung has a right to compete, it does not have a right to compete unfairly, by flooding the market with infringing products,” Judge Lucy Koh wrote. “As a patent holder, Apple has a valid right to exclude others from practicing Apple’s invention.”
The ruling won’t do immediate harm to Samsung, which filed an appeal five hours later. Stores that carry the device can continue to sell what inventory they still have, and the order does not affect the Galaxy Tab 8.9 or the Galaxy Tab 10.1N, an updated version designed to get around a similar ban in Germany.
Nonetheless, it’s an important ruling — symbolically and legally — and the timing is significant. Samsung is the only maker of tablets based on Google’s GOOG Android operating system to have made any headway against Apple in one of the fastest-growing markets for electronic devices, and the court found that it did so with a tablet “virtually indistinguishable” from the iPad.
Moreover, the injuction was issued just as the next generation of iPad competitors enters the market. Microsoft MSFT unveiled its family of tablets — dubbed Surface — last week, and Google is expected to introduce one of its own later today.
Ironically, the judge who handed Apple its first major victory in the U.S. for a design patent — as distinguished from a utility patent (see Apple’s secret weapon) — denied the “obvious validity” of the very same patent six months earlier.
