An Attempt to Cancel Patent For Breaking GSM Standard Algorithm

September 27, 2017

GSM logoDr Elad Barkan invented or discovered a cryptology method for breaking GSM coded communications and filed a patent application on 30 April 2003 titled “Cryptanalysis Method and System”, which was awarded Israel Patent No. IL 155671 in June 2005. The method was based on the discovery of a fundamental coding flaw in the GSM protocol which caused quite a stir among both telecommunication experts and the cryptology community.

DiscoveryOn 23 June 2015, Rontal Engineering Applications 2001 Ltd applied to have the patent cancelled on various grounds including that it was a discovery and not an invention, that the supplementary tests of inventiveness were met so that there was no inventive step, and that the patent was never implemented. In a long and detailed decision, Deputy Commissioner Ms Jacqueline Bracha considered the various allegations and ruled on the validity of the patent registration.

After the statements of case and the evidence were submitted, a three-day hearing was scheduled in December 2016, and the parties then submitted written summations.

Complicating matters, during the summation stage, the Opposer, Rontal Engineering Applications 200 Ltd filed for bankruptcy. Dr Barkan submitted a request that they post a bond for 200,000 Shekels, to pay his legal fees should he prevail against them. The Deputy Commissioner agreed with his request and a bond was posted on 15 July 2017.

Somewhat unusually, the ruling starts with a list of definitions of various words relating to the GSM protocol. Then the decision goes on to rule if the invention relates to patentable subject matter.  In a 46 page ruling with 165 paragraphs, the Deputy Commissioner found that the invention is patentable per se. Furthermore, the invention described is substantially different to the closest prior art so the patent was upheld.

In my conclusions at the end of this article, I conclude that the Opposers could probably have successfully obtained their real objective by negotiating a claim restriction to exclude brute force attacks which were never intended to be covered by the claims anyway.

A summary of the Decision follows.

Glossary

The patent relates to GSM encryption, and to understand the case, a number of terms need to be defined.

GSM NETWORKGSM is an acronym for Global System for Mobile Communications. It is a standard for cellular phone networks developed in 1987 and available since 1992. The standard was published before the priority date.The standard is a digital telecommunication standard and voice is digitized, transmitted and then converted back into sound. GSM is encrypted to prevent third parties from eavesdropping. The communication takes place via base stations.

DBS Satellite Services 1988 LTD provides satellite television services in Israel that are branded as YES. The Service is licensed by the Communications Ministry.

DBS Satellite Services 1988 LTD sued the brothers Ahmed and Amar Hamuda for trademark and copyright infringement and damages, requesting the following sanctions:

  1. A permanent injunction against the defendants to prevent them from distributing, marketing of selling pirate transmission of the Plaintiff, to cease using the plaintiff’s trademarks, including in third party publications. They requested an injunction against them using the plaintiff’s equipment, or equipment supplied by the plaintiff to their customers, for any but personal use, and to cease any non-personal use immediately.
  2. An order to the defendants or to the receiver to destroy all equipment that enables copyright infringement and all material carrying the YES logo.
  3. An injunction to remove YES’ registered trademarks from the FACEBOOK page for Acre Satellites and from all other publications.
  4. A request to reveal accounts going back seven years.
  5. Statutory damages of 700,000 Shekels under Section 56a of the Copyright Act and Statutory Damages of 100,000 Shekels for trademark infringements (claiming single infringements merely to reduce the court fees) and double costs as a punishment for willful infringement.
  6. Alternatively, compensation of 1,900,000 Shekels for Unjust Enrichment,  (the figures capped to reduce the court fees).

These injunctions were granted by Judge Zernkin, and following the Anton Pillar injunction, equipment and computer records were seized and a summary report was filed to the court by the receiver.

The injunctions were kept in force until the end of proceedings, and for the purposes of the hearing, an order to produce documents and to fill out questionnaires was issued.  This happened in the presence of the defendants who then failed to respond. Consequently, using powers under Section 122 of the Civil Court Procedure 1984, the court ruled that the statement of defense be struck from the record. It is noted that the statement of defense was a mere denial without any explanations.

In a ruling of 27 December 2014, Judge Orit Weinstein requested that the Prosecution supply evidence to substantiate their case and on 15 January 2015 they submitted evidence and affidavits of private detectives, by the VP (Engineering) of YES and the Head of Development at YES.

Based of the evidence submitted, Judge Weinstein ruled that there was sufficient grounds for a judgment against the defendants:

The Defendants broke the security encryption of the satellite transmissions and created a pirate industry, marketing and selling YES’ transmissions piratically, without paying YES, and by undercutting YES’ prices, free-riding on YES. YES’ copyright was infringed by the packaging of the transmission channels and the content, and YES’ trademarks were infringed by being used without permission and illegally.

Consequently, Judge Weinstein ruled that the temporary injunctions would become permanent injunctions, that all equipment be destroyed, following the receiver declaring that he was not holding any assets, there was no need to issue an order against him. The FACEBOOK page should be amended and so should all other publications so as not to include the trademarks of the plaintiff. Judge Weinstein further ruled statutory damages of 700,000 Shekels for copyright infringement and of 100,000 Shekels for trademark infringement, 10,000 Shekels expenses and 40,000 Shekels legal costs.

COMMENTS
I have no sympathy for the defendants in this case. Nevertheless, although the ruling seems very reasonable and the defendants didn’t exactly defend themselves, in the hands of a good lawyer, they could have raised a number of interesting questions. Free riding is not a crime. YES probably does not own very much of the copyright in their transmissions and creating a copyright in a package of channels is stretching things a little. In a recent Supreme Court Ruling concerning parallel imported Tommy Hilfiger shirts here, the Supreme Court allowed the parallel importer to advertise that it was selling Tommy Hilfiger shirts, but not to claim that it was a registered supplier, and to inform customers that they were not entitled to warranties from the official suppliers.  Can one really prevent someone from using the word ‘yes’ on their facebook page or in advertisements?

pirate

Piracy is the crime of boarding shipping on the high seas that is punishable under international maritime law by requiring the pirate to walk the plank.

Arguably with regular TV transmissions, there is a case for Ministry of Communications regulation to divide the radio frequencies into separate bands and to prevent channels interfering with each other. I am not sure that for digital signals sent by satellite this is the case. Certainly government tenders have been abused. The tender for commercial radio that then Govt. Minister Shulamit Aloni put together was designed to prevent Arutz 7 from obtaining a license. The same politicians who called the Arutz 7 team pirates and warned about pirate radios risking plane crashes lauded the late peace activist Abu Natan and his pirate radio ship the Voice of Peace and nominated him for a Nobel Prize. When the Supreme Court voted en banc against Arutz 7, without a dissenting voice even mentioning the value of free speech, it was clear that things have deteriorated a long way since Agranat’s deicison re Kol HaAm.


Israel’s Vringo Obtains injunction Against ZTE

December 17, 2013

VRingo

Vringo Inc. (VRNG) have announced that a Germany court found that Chinese telecommunications company ZTE Corp. (000063.SZ, 0763.HK, ZTCOY) infringed one of its European patents and is required to pay damages. The total amount of damages is still being determined. ZTE was also ordered to cease and desist distribution of base stations that were found to infringe Vringo’s patent. A ZTE representative wasn’t immediately available for comment.

Shares of Vringo, a small mobile technology and intellectual-patent firm, jumped 5.5% premarket to $3.25. As of Monday’s close, the stock was up 7.3% so far this year.

The court ruling is subject to appeal. Also, since Germany has a bifurcated system, the validity of the patent involved is being considered in a separate proceeding, as ZTE filed an action in a federal patent court in Germany trying to nullify the patent.

Vringo filed patent infringement cases against ZTE in five countries and has a preliminary inquiry in Spain. The patents involved relate to wireless infrastructure and handsets. The suits were filed in India, the U.K., Germany, France and Australia.

Last year, Vringo was awarded about $30 million in damages and granted future royalties by a federal jury in its patent suit against a handful of technology giants, including Google Inc. (GOOG) and AOL Inc. (AOL). Vringo had sued the search companies for allegedly infringing two of its patents related to advertising placement in search results.
