Varicom Communications LTD, an Israel company, http://www.varicom.co.il/ filed a patent application (number IL 135684) in Israel. The claimed invention was quite nifty. It allowed mobile phone owners to know who had tried calling them and when. Back in April 2000 when the application was filed, the idea was less obvious than it seems today.
Over the course of the year, the idea was developed somewhat, and a PCT application claiming priority from the Israel application but with added material, was duly filed.
A national phase entry into the US, number USSN 08/569,209, eventually issued as US 6,754,316, and the applicant requested allowance on the basis of the corresponding equivalent US Patent, conformed the claims and specification of the Israel application to that of US 6,754,316, and the patent was granted and published for opposition purposes.
Herein lies the problem. The additional material which is necessary to support the allowed claims is only entitled to the date when it was added, sometime in 2005, way after the PCT application published. Thus the PCT application became prior art to the invention and torpedoed the patent.
Comverse LTD http://www.comverse.com/, an International company with a large Israel presence, filed an opposition also claimed that prior art mentioned in the International Search Report of the PCT was not placed on record by the applicant during the Israel examination, contrary to Section 18 of the Law (duty of disclosure). They also claimed that a product of theirs – Trilogue INfinity Platform anticipated the application in its entirety, using affidavits to support their claims that the product was sold to clients before the priority date. The applicant did not respond to the opposition procedure so the historic truth of these allegations was not examined on their merits. This leaves the validity of Varicom’s corresponding US patent somewhat unclear.
The morals of the story:
- First filing in Israel is a great idea, as the application only publishes on allowance
- Adding material before filing a PCT or regular Paris convention applications is also OK, but amend the priority application to include the additions before the PCT or foreign filings publish 18 months from priority
- Cite everything of relevance under Section 18, and if adding the specification prior to allowance under Section 17c, check that anything relevant to the added material is also cited
- Be careful when invoking Section 17c
- Use counsel when fighting oppositions – Dr Oded Cafri, founder and president of Varicom didn’t use professional representation. Not a good idea.
- If you are caught out probably best to abandon the application rather than letting an opposition proceedings publish which is minimally embarrassing and potentially very damaging.
