TC 2800: The Workhorse

 

Technology Center 2800 handles semiconductor and electrical and optical system applications. Semiconductors are materials that have a conductivity between conductors (metals) and nonconductors (most ceramics). Their primary purpose is to fabricate computer chips used in a wide variety of electronic devices, including smartphones, computers, and radios. As such, they are vitally important to our modern connected lives and form a cornerstone of the tech economy. 

Perhaps reflective of this foundational importance is the number of applications TC 2800 receives. During the five-year period between 2013 and 2017, TC 2800 received a total of 357,174 apps, the most of any Tech Center at the USPTO during that time. Although it gets a substantial number of applications, TC 2800 is not a particularly difficult tech center to work in, as its average allowance rate is 88%—also the highest among utility tech centers at the USPTO. 

Thus, it is not unfair to say that TC 2800 is the workhorse of the USPTO. In the graphs below, we pull back the curtain to reveal prosecution trends that have occurred in TC 2800 during the five-year period between 2013 and 2017. Please note that all metrics herein are based on published applications only and do not account for all applications filed after the USPTO's 18-month publication delay period (in this case, January 2016). For more information, hover over each of the graphs or get started with Juristat.

Back to the list

 
To determine the top assignee filers in TC 2800 for this period, we measured the aggregate number of applications every assignee filed over the entire five-year period. The graph above shows how many applications each of those top five assignees filed per year during the period.
 
To determine the classes that received the most applications in TC 2800 for this period, we measured the aggregate number of applications every class received over the entire five-year period. The graph above shows how many applications each of those top five classes received per year during the period.
 
To determine the top firm filers in TC 2800 for this period, we measured the aggregate number of applications every firm filed over the entire five-year period. The graph above shows how many applications each of those top five firms filed per year during the period.
 
An application that is "disposed" is an application that has reached the end of the standard prosecution process, either by receiving a Notice of Allowance or through abandonment.
 
The number of applications filed per year in TC 2800 represents the total number of utility patent applications that all entities (both firms and in-house counsel) filed during the years highlighted.
 
A technology center's allowance rate is the percentage of applications that receive Notices of Allowance out of all disposed applications. TC 2800’s overall allowance rate, at 88%, is quite high, managing to easily beat the USPTO average allowance rate of 72%.
