The battle over claim term interpretation is a common challenge in patent prosecution. Read about a recent case at the PTAB and see the various ways that patent professionals can better combat an improper interpretation by an examiner.

Patent Drafting Tip - Even if it may seem verbose to explicitly describe detailed examples illustrating the inventive approach that seem obvious from the disclosure, failing to do so can severely limit amendment options when they are needed most during prosecution.

Read about how the problem-solution approach can enhance your software patent application, and see how the lack of such a strategy can lead to trouble at the PTAB.

Read about a recent PTAB case involving a baseball bat invention. The PTAB used the applicant’s specification to find an implicit definition of a claim term so as to reject the examiner’s overly broad interpretation.

While specifically claiming the training of machine learning models is one way to obtain patent eligible protection for machine learning inventions, it is not a silver bullet. Find out more in this post.

Can a generic statement that features from different examples can be combined qualify as disclosure sufficient the claim a specific combination of features across two examples? Find out what the PTAB thinks in a recent case.

Patent professionals often find themselves utilizing unexpected results as part of an argument. While unexpected results can be used as secondary considerations, the assertion that a claimed invention achieves an unforeseen outcome can sway the balance in favor of patentability even at the prima facia case. However, the subtle demarcation between "unexpected" and "different" is often muddled. Read the latest post and make sure you know the difference.

See the PTAB cite Schulhauser to require consideration of controller elements, showing that Schulhauser cuts both ways.

Check out the latest post on navigating the inherent ambiguity of language in patent claims that considers how trying to claim the performance of an action regardless of a condition is no limitation at all.

As illustrated by a recent PTAB case determining the patentability of an absorbent pad pattern, patent professionals must retain vigilance and adaptability, particularly when it comes to anticipating the potential application of the printed matter doctrine in novel contexts.

Read about a PTAB case where the term environment was interpreted broadly enough to cover anything in the surroundings of a user as a user surroundings. That means even the ants on the ground qualify. See if you agree!

Does labeling a figure or embodiment or related description as “schematic” mean that such disclosure is unavailable for establishing written description support under 35 USC Section 112? Surprisingly, some patent examiners, and some of the supervisors, think so.

Read about a case where a patent applicant argued the examiner’s interpretation was too broad but then was burned by their own specification defining the scope to expressly include something that they argued was excluded. Make sure you read your whole specification whenever there is an interpretation issue - even if the examiner did not, the PTAB will.

Read about a recent case where the interpretation of a claim term under broadest reasonable interpretation has downstream impacts on the non-analogous arts test. Decide for yourself whether you would consider a soup with sour cream within the field of citrus beverages.
