Beware of Conditional Limitations when Drafting Patent Claims

Buried in the claim language, conditional limitations may be a vulnerability in an otherwise valuable claim. A conditional limitation is a claim feature that depends on a certain condition being present. For example, when or if condition X is present, feature Y is implemented or has effect. Without condition X, feature Y may be dormant or have no effect. Patent owners should be cognizant of possible conditional limitations implications because conditional limitations may affect claim validity and infringement as discussed below in the context of recent U.S. Patent Office and Federal Circuit cases. In Ex Parte Schulhauser, the Patent Trial and Appeal Board (“the Board”) held certain claims as unpatentable based on conditional limitations.

Requisites of a Patent Application: Claims and drawings technically not required on filing date

For as long as I can remember, in order for a nonprovisional utility patent application to be awarded the all important filing date you had to file a specification that adequately described the invention, at least one patent claim and at least one drawing if a drawing would facilitate in the understanding of the invention. Spec, claim, drawing was beaten…

An Examiner’s Tips For Speedier Patent Prosecution

Interactions between patent examiners and patent practitioners are often tense. At worst, these interactions can be an exercise in restraint with both parties thinly veiling their disdain for one another. This adversarial approach can stall prosecution and run adverse to the practitioner’s purpose – i.e., to obtain the best patent claim scope possible for his or her client. Patent practitioners thus could benefit in many instances by having a better understanding of an examiner’s expectations and approaching prosecution with a mind toward working with the examiner instead of against the examiner. A conversation with an Examiner in a mechanical art unit provided the following tips for how practitioners may expedite the examination process by working (to the extent possible) within the examiner’s expectations.

An Introduction to Patent Claims

The examination you receive from the patent examiner is never going to be any better than the patent claims you provide. If you provide preposterously broad patent claims and then add very few and perhaps common features to that preposterously broad claim in your dependent claims you are making it easy for the patent examiner to reject the preposterously broad claim and then also reject your barely narrowing dependent claims. Worse, you are left with absolutely no useful information about what the patent examiner thinks might be patentable. You are not in a meaningful position to know what prior art exists that the examiner will later throw at you, and you hardly have any useful basis to talk to the patent examiner.

Pursuit of Extremely Short Patent Claims

Dear Patent Attorney, Please stop filing extremely short, overly broad patent claims. I recently conducted a study to measure the effectiveness of various prosecution strategies. The study covered over a hundred thousand patent assets pursued by software companies, and for this sample, I found that filing extremely short, overly broad patent claims is a bad strategy in just about every way imaginable.
