In a clear indication of the controversial nature of the new rules announced in August, the U.S. District Court for Northern Virginia issued a preliminary injunction enjoining the USPTO from implementing the new "final" rules just one day before they were to become effective on November 1, 2007.
The challenge to the new rules by SmithKline Beecham Corporation and Mr. Triantafyllos Tafas is primarily based on the argument that the USPTO has overstepped its rule-making authority and that the final rules cannot be implemented without a change in the US patent law by the US Congress. Other arguments allege that the retroactive effect of the new rules deprives applicants of the rights they had at the time of filing, and that the new rule changes are arbitrary and capricious.
In response, the USPTO asserts that the new rules do not eliminate any existing rights, but merely up the requirements for their assertion; and that the plaintiffs are not actually asserting any rights, but complaining about unmet expectations. The court held that the evidence did not show the USPTO rules to be arbitrary or capricious at this preliminary stage of the proceedings.
The preliminary injunction is meant to retain the status quo until the District Court has had time to hear and evaluate all the evidence, and make a final ruling on the issue. The USPTO may revise the final rules to remove the most egregious and controversial provisions; it may also appeal the preliminary injunction.
In accordance with the District Court ruling, the USPTO has directed its Examiners to follow the existing rules until further notice.
