Mission Impossible? How to Effectively Draft the Background Section of a Patent Specification in Compliance with Both USPTO and EPO Practice

Preparation of the background section of a specification that complies with the requirements of both U.S. Patent and Trademark Office (USPTO) and European Patent Office (EPO) requirements is a classic conundrum for patent drafters seeking to file an application in both jurisdictions via the Patent Cooperation Treaty (PCT) or direct filings. In U.S. patent applications, statements made in the background section can be considered an admission of prior art, regardless of whether the admitted prior art would otherwise qualify under 35 U.S.C. 102 and regardless of any disclaimer made. Additionally, statements made in the background section of an issued U.S. patent can not only be used against expert testimony that describes the prior art differently and during claim construction, but also can have a limiting effect on claim interpretation. As a consequence, discussion of deficiencies in the prior art can be interpreted as a disclaimer of the related features and therefore can severely (and often inadvertently) limit the interpretation of the claims. In contrast, statements made in the background section of EPO applications that discuss deficiencies and technical problems present in the prior art are expected to be included in order to enable the reader to understand the technical contribution to the art made by the invention as claimed. In particular, according to EPO practice, the applicant is expected to discuss the technical problem solved not just in view of the closest prior art at filing (subjective technical problem), but also, more importantly, in view of the prior art cited during prosecution in the context of the problem-and-solution approach (objective technical problem). Accordingly, applicants drafting applications to be filed at the EPO tend to provide a heavy background section with discussions of cited documents, related deficiencies and problem solved and later adjust it in view of the objective technical problem in view of the objective technical problem arising during prosecution. What constitutes best practice in this scenario and how the two practices can be harmonized is controversial.

Intellectual Ventures v. T-Mobile: Summary Judgment of Non-Infringement Vacated Due to Incorrect Claim Construction

In claim construction analyses, the plain and ordinary meaning of a claim term will not be narrowed by statements in the prosecution history, unless those statements clearly and explicitly evidence the patentee’s intent to depart from the full scope of the claim. If a dependent claim includes the purportedly disclaimed subject matter and was added at the time of the purportedly disavowing statements, a finding of disavowal is unlikely. Furthermore, a means-plus-function term should clearly and objectively define the function of the limitation; if the function is a subjective term of degree, a finding that the term is indefinite is likely.

Federal Circuit Decisions Breathe New Life Into Alice Responses by Patent Prosecutors

While most commentary to date has focused on the implications for litigation, two recent Federal Circuit decisions have promising implications for patent prosecutors struggling to overcome conclusory rejections that claims lack subject matter eligibility.  Since Alice and the subsequent interim guidance by the U.S. Patent Office, one aspect of subject matter eligibility determinations that has frustrated patent prosecutors has been the fact-free, conclusory analysis commonly provided.  However, the Federal Circuit’s February decisions in Berkheimer and Aatrix conflict with the Patent Office’s guidance that “judicial notice” fact-finding is sufficient for subject matter eligibility rejections, and the substantial evidence standard applicable to administrative fact-finding during examination does not comport with the underlying “examiner expertise” rationale for that guidance.

Admissions as Prior Art in a Patent: What they are and why you need to avoid them

So what is an admission? A statement made during patent prosecution identifying the work of another as prior art is called an admission. Admissions can and will be relied upon by patent examiners for both novelty (35 U.S.C. 102) and obviousness (35 U.S.C. 103) determinations, regardless of whether the admitted prior art would otherwise qualify as prior art under the express terms of the statute. Admissions should be avoided at all costs, regardless of how innocent they seem to be. This is a lesson that all new patent practitioners and inventors need to take to heart. No matter how innocuous the statement may seem, always remember that no good deed will go unpunished! Everything you do say can and will be used against your patent once it issues — forever.

Testing a Patent Claim against an Abstract Idea, in Response to 35 USC §101 Rejection

One promising approach is to argue that the claims are directed to a specific technological solution to a specific technological problem, as has been successful in the courts. But, even this may not be convincing, if argued in the abstract, because, after all, we are dealing with abstract ideas to begin with, and it is all too easy for an examiner to dismiss an abstract argument as “not convincing”. A concrete, bright line test can be constructed, which may sway an examiner (or appeal board, if the rejection is appealed). Articulate a specific technological problem that the claims solve or are directed to solving. Analyze the claim and cite some of the important claim limitations that are not present in the alleged abstract idea, and explain the significance of these claim limitations in terms of the technological problem and technological solution.
