When a rule becomes a target, it ceases to be a good rule.  In the three years since the Supreme Court issued its opinion in Alice, there have been positive changes to patent applications, but there remains a long-term risk that patent practitioners will use tricks to beat the Alice test.  Here, we focus on the changes to patent applications by drafters, as well as changes to patent applications that have issued since Alice… Previous analyses have reported that patent specification length has been increasing since long before 2010. As shown in Figure 3, from 2010 to 2013, the average patent application length was approximately 12,417 words. However, from 2015 and 2017, the average patent application length increased to over 14,700 words… Alice appears to have resulted in positive developments, such as narrowing the scope of claims and increasing disclosure of technical benefits of inventions in the specification.

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.

Drafters need to think both outside and inside the claims. Outside thinking aims to make the court’s task easier by providing claim terms amenable to straightforward, simple claim construction. Preferably, at least, the key terms are expressly defined, or at least explained through demonstration. Inside thinking takes up the question whether the claim construction supports the patentee’s or owner’s intention, as manifested in the claims and specification. By the time a drafter is “experienced,” she has been exposed to considerable instruction on claim drafting. Claim construction rules, claim drafting principles, claim drafting strategy—the endless seminar. Yet, the Federal Circuit regularly lectures the patent bar on its drafting practices. The difficulty is that among all of our construction rules and strategic principles, we have lost sight of clarity and precision. We need to refocus on basic principles. Indeed, we’re going to need a bigger boat.
