    I don’t think quantity is correlated with quality beyond a bare minimum level of quantity.

  2. AAA JJ March 1, 2018 8:41 am

    As Joe Stalin said, “Quantity has a quality all its own.”

  3. Anon March 1, 2018 9:45 am

    (along the lines of “you get what you measure”)

  4. Gene Quinn March 1, 2018 10:35 am

    I understand that quantity is not a measure of quality, but I do think this information is still at least interesting. And to some extent quantity must mean that at least some clients view the firm as doing work that is quality enough. And the firms that rank the highest are likely the ones doing the most foreign work and have developed a prosecution-style business. So I think the list is good for what it is.

    Having said that, I continue to try and think of a way to identify quality. I’d love to be able to come up with a way to identify quality work of individual attorneys in different disciplines. That would almost certainly require some kind of an application process because it just isn’t feasible to review hundreds of thousands of applications/patents a year, and even if we could the name of the attorney doing the work isn’t always on the patent/application.

    If anyone has any thoughts on how to legitimately recognize quality I am all ears.

    Gene@4

    Incredibly difficult question given so many variables. On the extremities to the question of how good the work is are biases in the system (which examiners, what technology group, the “patentability” weather for subject matter of certain technologies and how that plays out at the USPTO and courts) and the level of inventiveness (foundational versus incremental), complexity, subtlety of the particular invention… so the “player” has to do what he/she can 1) in varyingly biased arenas of differing difficulty and 2) starting with something he/she has no control over. We could assume each firm has an equal distribution of technology areas and inventions of similar quality but that is a fiction, especially if firms focus on specific technology or tend to serve only large or small clients, established or new companies … etc.

    With respect to allowance, worthless patents with overly narrow claims are easier to patent than valuable patents with broad claims.

    If one were for example only to look to licensing and litigation outcomes (measured monetarily), one has to take into account the licensing team, and the litigation team as playing a large factor. Moreover, the amounts involved are in large part a reflection of the market share (or portion) of the particular products which the claimed invention reads on, and not a reflection of the patent as such.

    Another problem, you identify is true also, the name of the attorney doing the work does not always appear on the patent/application.

    I think the task of assessing an individual attorney is a hopeless task without taking a brute force approach of looking through the applications and prosecution by that attorney in substantive detail.

    Taking a huge step back, I think the only way to get any idea of a firm, is to look at how well the firm is doing overall, if clients are succeeding, making money, and are happy with the work, then the firm should be making money, expanding, hiring more attorneys, and they should be succeeding over the long term. I think (unfortunately) these are the probably the only reliable ways to judge, is to judge a firm on average.

  6. Curious March 1, 2018 12:02 pm

    I think the task of assessing an individual attorney is a hopeless task without taking a brute force approach of looking through the applications and prosecution by that attorney in substantive detail.
    That’s pretty much it. Even then, you also need to understand the client’s objectives. Different clients have different goals that impact how an application is to be prosecuted. Some clients want the broadest claims — period. Some claims want broad claims but also want allowances. Some clients are all about allowances and don’t care about claim coverage. Some clients want all three at different times. Unless you know what the client wants, you cannot understand what the attorney is attempting to accomplish.

    Again, it makes identifying very good attorneys from good attorneys very hard. That being said, it is pretty easy to spot bad attorneys. Bad attorneys make bad arguments (i.e., arguments that have no shot of prevailing) and miss easy arguments. Bad attorneys craft undecipherable claims and add unnecessary limitations. Also, when I say “bad attorneys” I don’t mean that they inherently incompetent. Like anything, how one approaches his/her job is likely based upon his/her training. A very smart young attorney trained by an incompetent attorney is going to have a harder go at it than an average attorney trained by someone very competent. As an attorney, you can still overcome a bad trainer — it just makes the job harder.

    Also, when it comes to law firms, they are almost all little fiefdoms. Some are good, some as bad. Especially with a big firm, you can have excellent attorneys sitting right next door to bad attorneys. This doesn’t necessarily always apply, but one should always strive to hire an attorney — not a law firm.

  7. Anon March 2, 2018 8:13 am

    I completely agree with Curious, and would amplify the overall nature of the practice of law as being practically feudal.

    I come into law after careers in tech and management, with degrees and Deming training.

    What I see in law firms is an overall lack of appreciation of management theory.

  8. Curious March 2, 2018 9:02 am

    What I see in law firms is an overall lack of appreciation of management theory.
    Law firms are mostly run by people with BAs who get away with terrible business practices because a large law firm (with decent clients and plenty of associates, a.k.a., leverage) essentially has a license to print money.

  9. EPAttorney March 2, 2018 9:22 am

    Hey, at least you’re open with your criteria, albeit rather unscientific as already discussed above. I wonder if the other law firm directories could be so open with their measures? Oh yeah, you have be a good buddy of the editor….that’s it!

  10. Frank Stapleton, DDS March 6, 2018 11:44 pm

    I would give my shout out to Ed Bannon and his team at Fish & Richardson for the great job they did at helping me secure my patent this past December.
