//The Largest US Patent Law Firms

Country Report: The Largest US Patent Law Firms

Who are the largest US patent law firms? How do they differentiate in patent filing strategies and client structure?

Analyzing their filing statistics, this report is shedding the light on the largest patent law firms in the United States. The figures are based on patent filings since 2014 and contain published patent applications as well as granted patents. If not stated otherwise, the numbers are based on US national filings as well as PCT applications filed by US law firms.

In order to allocate patents to the respective years, we use a mix of patent filing dates and dates of the earliest publication. Whenever an application is itself the priority filing, a direct US foreign filing or a PCT application filed by a US law firm, we refer to the application filing date. However, when a US application is a subsequent of a foreign priority and filed on the PCT route, we use the earliest publication date. This distinction is necessary because, in the raw data, US patents in the latter category usually receive the filing date of the underlying PCT rather than the actual filing date of the US national filing. The earliest publication date is much closer to actual time a US law firm has worked on the national filing.

In most cases, patent information are published 18 months after they have been filed. Therefore, figures cannot yet be complete for 2017 applications/grants. We have included all the latest publications we have available until now.

 

The largest US Patent Law Firms: Who are they and how did they develop over time

With over 27,000 patent filings, OBLON, MCCLELLAND, MAIER & NEUSTADT, LLP has been the most active IP law firm in the US since 2014. On average, they represented 7,200 applications per year between 2014 and 2016. Oblon was number 1 in 2014 and still is on top of the list in 2017.

SUGHRUE MION, PLLC comes in second with 19,000 filings and roughly 5,400 filings per year. They, too, kept this rank over the full period. However, the difference of 8,000 filings is substantial. It is roughly the number of applications a law firm around rank 17 has done overall in this decade.

KNOBBE, MARTENS, OLSON & BEAR, LLP is on rank 3 with more than 18,000 applications.

Ranks 4 to 8 belong to 5 law firms with roughly the same number of filings: FISH & RICHARDSON, CANTOR COLBURN LLP, HARNESS, DICKEY & PIERCE, P.L.C.BIRCH, STEWART, KOLASCH & BIRCH, LLP and OLIFF PLC  all represented around 16,000 applications. The top 10 is completed by FOLEY & LARDNER LLP and KILPATRICK TOWNSEND & STOCKTON LLP. They filed roughly between 3,800  and 4,000 applications per year each.

Ranks have varied over the last decade, but most of the time these firms remained among the top 10 year by year. KILPATRICK TOWNSEND & STOCKTON LLP was the only firm to show a significant leap. They jumped from position 16 in 2010 to position 9 in 2016. This seems to result from the merger of Kilpatrick Stockton and Townsend and Townsend and Crew into one joint firm in 2011.

In order to receive a rank in the top 20 a firm had to have at least 7,000 filings (or 2,000 filings on average per year), while 4,600 filings overall or 1,200 filings per year were necessary to rank among the top 50.

While these overall quantitative statistics are interesting to look at in order to understand the size and volume of an IP firm, they do not tell much about the filing strategies or client structure. We see significant differences on how the firms act and we will discuss that by distinguishing between filings for domestic clients (i.e. priority filings and domestic subsequent filings) and filings following a foreign priority.

 

Domestic vs. foreign filings of the largest Patent Law Firms in the US

FISH & RICHARDSON and KNOBBE, MARTENS, OLSON & BEAR, LLP , KILPATRICK TOWNSEND & STOCKTON LLP and SCHWEGMAN, LUNDBERG & WOESSNER, P.A. are the largest patent law firms in the US when taking solely domestic filings into account. Each of them were involved in at least 11,000 applications where the firm filed the priority application.

The firms leading the overall table do so because of foreign filings they take over from IP firms or IP departments who filed the priority application abroad. They are very successful in attracting business from foreign clients rather than working with local US clients (or US subsidiaries of multinationals). The top 4 overall law firms all have foreign filing ratios of 88% and above, i.e. 9 out of 10 cases come from abroad. In comparison, the top domestic representatives have ratios between 9% (SCHWEGMAN, LUNDBERG & WOESSNER, P.A.) and 45% (CANTOR COLBURN LLP).

The largest overall patent law firm, OBLON, MCCLELLAND, MAIER & NEUSTADT, LLP, ranks only 26 in domestic filings and BIRCH, STEWART, KOLASCH & BIRCH, LLP, overall on rank 3, is only number 179 in domestic filings.

On the other hand, for example, SCHWEGMAN, LUNDBERG & WOESSNER, P.A., number 4 in domestic filings, is only number 118 in foreign filings. Whether the reason lies in strategic positioning of the firm or in historically developed client structures, depends on the firm. However, these figures show substantial differences in the applications they represent on behalf of their clients.

 

PCT vs. national US patent applications filed by the largest US Patent Law Firms

With rather few exceptions, US IP firms will not be involved in filing a PCT application, if the filing process has been started abroad. The local representative usually files a PCT on behalf of their client. So, PCT applications are mostly filed for domestic mandates. Unsurprisingly, if a firm mostly works on foreign filings, we see a very low share of PCT applications among the overall filings. Consequently, if a firm ranks high on US filings, it will rank high on overall filings.

For top 4 firms, who we already identified as mostly active in foreign filing (OBLON, MCCLELLAND, MAIER & NEUSTADT, LLP, SUGHRUE MION, PLLC, KNOBBE, MARTENS, OLSON & BEAR, LLP and BIRCH, STEWART, KOLASCH & BIRCH, LLP), we see a PCT ratio of below 1%.

Firms among the top 20, who tend to have a significant share of domestic filings, tend to show a PCT ratio between 10 and 20%.

However, a ratio of PCT filings over domestic filings could be expected to be similar for all firms. This is not the case. The big four show ratios of 8-13%, while firms with a strong domestic filing business usually range between 21% and 26% of PCT filings among domestic filings. An interpretation would be that firms with a strong international business tend to advise their domestic clients against PCT applications (in favor of direct filings). Alternatively, this could mean that they work for clients who(se IP departments) themselves prefer direct filings over the PCT route.

BANNER & WITCOFF, LTD. is the only a notable exception. They rank on position 7 for domestic filings, but their PCT over domestic filings ratio is not more than 10%.
