Starsight Telecast Inc & Anor v Virgin Media Ltd & Ors

Factual and Procedural Background

The Claimants, collectively referred to as "Plaintiff", are members of the Rovi group of companies. The Defendants, collectively referred to as "Defendant", are members of the Virgin Media group, with the Third Defendant providing hardware and software for certain set-top boxes ("STBs") supplied by Defendant to their customers. This is the third legal action between these parties concerning television electronic programme guides ("EPGs").

Plaintiff alleges that Defendant infringed two European patents ("the Patents"): European Patent (UK) No. 1 763 234 ("234") and European Patent (UK) No. 0 821 856 ("1856"). Two classes of allegedly infringing devices are at issue: the TiVo STB, alleged to infringe both patents, and the VHD and V+HD STBs (collectively "VHD"), alleged to infringe only patent 234. Defendant denies infringement and counterclaims for revocation of the Patents on multiple grounds. The priority dates of the patents are not challenged.

The trial commenced on 26 February 2014 with a planned schedule of witness evidence and submissions but encountered delays primarily due to Defendant's inadequate product and process descriptions ("PPDs"). Further information was requested by Plaintiff, leading to several addenda and witness statements from Defendant before the trial concluded on 11 March 2014. The court found Defendant mainly responsible for the trial's disruption, though Plaintiff contributed.

Legal Issues Presented

1. Whether Defendant infringed the patents held by Plaintiff.
2. Whether the patents are valid, considering grounds such as added matter, obviousness, novelty, excluded subject matter, and extension of protection.
3. Interpretation and construction of patent claims, including the scope of terms such as "program schedule information," "sources," and "source devices."
4. Whether the Defendant’s products fall within the scope of the claims as construed.
5. Whether Defendant’s product and process descriptions complied with procedural rules.

Arguments of the Parties

Plaintiff's Arguments

• Plaintiff contended that Defendant infringed the asserted patents via the TiVo and VHD STBs.
• Plaintiff argued for a broad construction of the claims, including restricting access to program schedule information and program content.
• Plaintiff maintained that the granted claims and their proposed amendments were valid and that Defendant's products fell within their scope.
• Plaintiff relied on expert evidence to support the inventive concept and to counter Defendant's obviousness and added matter arguments.

Defendant's Arguments

• Defendant denied infringement and counterclaimed for revocation of the patents on grounds including added matter, obviousness, lack of novelty, excluded subject matter, and extension of protection.
• Defendant contended that the granted claims and combination claims contained added matter and were obvious over prior art including Bestler, the Davis Demonstration, and the Uniden 4800 device.
• Defendant submitted that the patents did not disclose a technical contribution beyond excluded subject matter such as presentation of information or computer programs as such.
• Defendant argued that their products did not infringe the claims as construed, particularly pointing to differences in how parental controls were implemented and the sequence of steps performed.
• Defendant’s product and process descriptions were initially inadequate, causing procedural difficulties during the trial.

Court's Reasoning and Analysis

The court began by reviewing the procedural history, particularly the inadequacies in Defendant's product and process descriptions (PPDs), emphasizing the legal requirements under CPR rule 63.9 and Practice Direction 63 for full and complete disclosure sufficient to resolve infringement issues. Defendant’s failure to provide adequate PPDs caused trial delays and increased costs.

The court then considered the technical background to the patents, including the state of television broadcasting, set-top box technology, conditional access systems, and electronic programme guides (EPGs) as of the priority dates.

Regarding patent 234, the court analyzed the claims and specifications in depth, focusing on parental control features for restricting access to program schedule information and programs themselves. The court construed key claim terms, rejecting Plaintiff’s broadest interpretations where unsupported by the specification and claims. In particular, the court held that the claims require that entering a code enables viewing of restricted information without disabling parental controls entirely, and that claims do not contemplate restricting access to program titles by removing them from the guide entirely.

On added matter, the court agreed with the Opposition Division that certain granted claims and their combinations contained intermediate generalisations not directly and unambiguously disclosed in the original application, rendering them invalid. However, the EPO claims were upheld against added matter objections.

On obviousness, the court found that both the granted and EPO claims were obvious over prior art including Bestler’s 1993 paper and the Davis Demonstration. The granted claims were also obvious over the Uniden 4800 device, while the EPO claims were not. The court carefully analyzed the disclosure of Bestler, concluding that it suggested parental control extended to individual programs using PIN codes and relational databases, which formed part of the common general knowledge. The Davis Demonstration further supported obviousness, although it did not disclose restricting access to program schedule information.

Regarding excluded subject matter, the court held that if the granted claims were valid, their contribution was an abstract idea of restricting display of information, falling within excluded subject matter (presentation of information), lacking technical contribution. The EPO claims, construed more narrowly, were found to have a technical contribution.

On infringement of patent 234, the court found that the Hide Adult Channels and Hide Adult Listings functions of the TiVo and VHD STBs did not infringe the granted or EPO claims, as these functions operated on a channel-by-channel basis without restricting individual program information or directing the display generator as claimed. The Alternative Adult Listings Display feature infringed the granted claims but not the EPO claims.

For patent 1856, the court construed the claims relating to multi-source television signals, clarifying terms such as "sources," "source devices," and "transmission schemes." It held that the skilled team would understand these as different devices and transmission methods (e.g., cable, satellite, terrestrial).

The court found that the claims lacked novelty over the Uniden 4800, which delivered television signals from multiple sources using different transmission schemes. The claims were also obvious over the Uniden 4800 and the Young patent, which disclosed switching between over-the-air and cable signals and the use of source identifiers.

On infringement of patent 1856, the court concluded that the TiVo STB did not infringe the claims, as it had a single source and transmission scheme (QAM modulated coaxial cable), and the data representing program information was downloaded rather than telecast. The TiVo STB did have an emitter, but the claim was not infringed for these reasons.

Holding and Implications

Patent 234:

• Granted claim 1 and the combination of claims 1, 2, and 4 are invalid due to added matter; the EPO claims are not invalid on this ground.
• Both the granted and EPO claims are obvious over the Bestler paper and the Davis Demonstration; the granted claims are also obvious over the Uniden 4800, but the EPO claims are not.
• If the granted claims were valid, Defendant’s Alternative Adult Display method of the VHD STBs would infringe, but the Hide Adult Channels/Listings functions of the TiVo and VHD STBs would not.
• Even if the EPO claims were valid, Defendant would not have infringed them.

Patent 1856:

• The patent is not invalid on grounds of added matter or extension of protection.
• All claims lack novelty over the Uniden 4800 and are obvious over Young.
• Even if valid, Defendant would not have infringed the claims.

The direct effect of this decision is that Plaintiff’s claims for infringement fail on both patents. The court’s detailed analysis clarifies the construction of the claims and the application of patent law principles such as added matter, obviousness, novelty, and excluded subject matter in the context of interactive EPG technology. No new precedent is established beyond the application of established legal principles to the facts of this case.
