Factual and Procedural Background
This is an appeal against the rejection of UK Patent Application No. GB 0723964.3 filed by Company A. The Hearing Officer, acting for the Comptroller General of Patents, rejected the application on grounds relating to the patentability of computer programs as such. The appeal focuses primarily on claim 33 of the application, which concerns a system for monitoring electronic communications to protect users, such as children, from inappropriate content. The system uses a data communications analysis engine employing hash tables to score data packets and generate alert notifications to a user or administrator, such as a parent, who can then remotely respond with actions including alerting a user, terminating communication, or shutting down equipment.
The Comptroller originally relied on exclusions relating to computer programs and mental acts but later withdrew reliance on the mental act exclusion following a recent judgment, focusing the appeal solely on the computer program exclusion.
The Appellant contended that claim 33 is novel and inventive, with the process operating more rapidly and reliably than prior art. The Examiner had acknowledged novelty and inventiveness over cited prior art, specifically noting the hash table approach's potential to reduce analysis time.
The Appellant requested allowance of claim 33 as filed or with amendments, including a feature enabling automatic shutdown of user equipment if no response is received within a predetermined time. Amendments to earlier claims were also proposed to include automatic transmission of alert messages to a remote terminal.
Legal Issues Presented
- Whether claim 33 of the patent application is excluded from patentability as a computer program as such under section 1(2) of the Patents Act 1977 and Article 52 of the European Patent Convention.
- Whether the contribution of claim 33 constitutes a relevant technical effect or technical contribution sufficient to overcome the computer program exclusion.
- Whether the mental act exclusion applies to claim 33, given the Comptroller's withdrawal of reliance on this exclusion prior to the appeal hearing.
- Whether the proposed amendments to claim 33 and earlier claims address the outstanding objections and support patentability.
Arguments of the Parties
Appellant's Arguments
- Claim 33 is novel and inventive, providing a monitoring process that operates more rapidly and reliably than prior art.
- The improved speed and reliability in processing expressions lead to faster and more reliable alarm notifications.
- The Hearing Officer erred by analyzing claims 20 and 33 separately, failing to consider claim 33's contribution as a whole, including the improved alarm notification.
- The generation and transmission of an alert notification to a remote terminal (e.g., a mobile device) is qualitatively different from mere display of information and constitutes a physical, technical effect outside the computer.
- The contribution of claim 33 includes an improved monitoring system with a technical effect beyond the computer program exclusion.
- The proposed amendments to claims 1, 5, 20, and 33 should be allowed to address outstanding objections.
Comptroller's Arguments
- Claim 33 is excluded from patentability as it relates solely to a computer program as such.
- The mental act exclusion no longer applies as the Comptroller withdrew reliance on it following recent case law.
- The contribution of claim 33 amounts only to informing a user/administrator of the result of data analysis, which is not a technical process but an aspect of program design.
- The generation and transmission of alert notifications do not constitute a relevant technical effect outside the computer.
- Reliance on decisions such as Mann J's judgment in Gemstar supports rejection of claims that merely display information or perform abstract tasks.

Application by the Court |
| Aerotel v Telco / Macrossan's Patent Application [2007] RPC 7; [2007] EWCA Civ 1371 |
Four-step approach for assessing patentability where exclusions apply: (1) construe claim; (2) identify contribution; (3) check if contribution falls solely within excluded subject matter; (4) assess if contribution is technical in nature. |
The court applied this approach to identify the contribution of claim 33 and assess whether it fell within excluded subject matter, ultimately finding that claim 33's contribution was not solely excluded. |
| Symbian v Comptroller-General [2009] RPC 1; [2008] EWCA Civ 1066 |
Guidance on the meaning of "technical" for computer program exclusions; no bright line test; case-specific analysis required. |
The court relied on this guidance to evaluate the technical contribution of claim 33, emphasizing the need to consider the invention as a whole and its technical effects. |
| ATT&T Knowledge Ventures [2009] EWHC 343 (Pat) |
Identification of signposts indicating relevant technical effect, including effects outside the computer, architectural changes, new computer operation, increased speed or reliability, and problem-solving beyond circumvention. |
The court used these signposts to assess claim 33, concluding that the invention solved a technical problem outside the computer, such as improved alarm generation. |
| Halliburton Energy Services' Inc's Application [2011] EWHC 2508 (Pat) |
Approved a narrow interpretation of the mental act exclusion; emphasized the need for a technical contribution for patentability of computer programs. |
The Comptroller withdrew reliance on the mental act exclusion based on this decision; the court focused solely on the computer program exclusion in the appeal. |
| Gemstar-TV Guide International Inc v Virgin Media Ltd [2010] RPC 10; [2009] EWHC 3068 (Ch) |
Assessment of technical effect in patents relating to electronic programming guides; distinguished between abstract effects (e.g., display changes) and physical effects (e.g., data movement). |
The court distinguished claim 33 from the Gemstar patents, finding that the alert notification and improved monitoring system constituted a physical, technical effect beyond mere display. |
Court's Reasoning and Analysis
The court began by identifying the contribution of claim 33, noting that the Hearing Officer had separated the contributions of claims 20 and 33 and overlooked the improved speed and reliability of the alarm notification system as part of claim 33's contribution. The court held that the improved alarm notification was novel and inventive and formed part of the contribution to human knowledge.
The court then reassessed whether the contribution fell solely within excluded subject matter. It rejected the Comptroller's submission that claim 33 was merely informing a user/administrator and that such informing was not a technical process. The court distinguished claim 33 from cases where the output was merely a display, emphasizing that the alert notification to a remote terminal was a physical concept with real-world effects, akin to the patentable third patent in Gemstar.
Applying the signposts from ATT&T Knowledge Ventures, the court found that the invention solved a technical problem outside the computer, specifically improving the generation of alarms for inappropriate communications. This was sufficient to overcome the computer program exclusion on the facts of the case.
The court noted that the mental act exclusion was no longer relied upon by the Comptroller and thus did not consider it further. It also indicated that amendments to other claims were necessary due to outstanding objections, and the matter was to be remitted to the Patent Office for further consideration, including harmonizing claim language.
Holding and Implications
The court's final decision was to ALLOW THE APPEAL in relation to claim 33 and remit the matter to the Patent Office for consideration of proposed amendments and outstanding objections.
The direct effect of this decision is that claim 33, as construed to include the improved alarm notification system, is not excluded from patentability as a computer program as such. The decision does not establish a new precedent but applies existing legal principles to the specific facts of this case, emphasizing the importance of recognizing technical contributions that solve problems outside the computer itself.
