Which are the Top Patent Prosecution Firms in Germany?

Encompassed in beautiful alpine ranges, Germany – the second-largest country in Europe – boasts not only of scenic beauty but is also an important hub of innovation. Home to major pharmaceutical and automobile manufacturers, the country has been a center of innovation in Europe for decades.

When we are discussing the innovation quotient of a country, looking at its patent prosecution trends provide a great outlook on the direction of research in the nation. It indicates how patents are being filed during a period which helps us judge the way a country is progressing technologically.

Where there are patent filings, there are law firms and attorneys involved. Thus, to find what they are up to and how the state of patent prosecution looks like in Germany, we used Thomson Innovation to extract the data of patents filed in Germany during the period of 2010-2015.

The key metrics that we used to derive our insights are as follows:

  • An overview of the Patent filing trend: The total number of patents filed for a period of time is a key indicator of the state of innovation in the country.
  • Resident vs. Non-resident patents: This criterion provides great insight into the research activity done by the local companies in comparison to the foreign companies.
  • Prosecution Trend: The prosecution trend helps to understand the landscape of the German law firms that are involved in a patent filing in the country. We have further divided this into two parts:
    • Top Law Firms associated with German Companies: The metric would help understand the law firms that are involved in filing patents for the innovation done within Germany.
    • Top Law Firms associated with foreign companies: The metric would help understand about firms that cater to foreign clients.

The above metrics, other than helping understand the patent prosecution trend in Germany, also helps compare how strategies of different law firms vary based on the type of clients they deal with.

Patent Filing Trend

Before we get started with the law firms’ stats, let us first look at how IP is growing in Germany. The chart below represents the overall patent filing trend in Germany from 2010 to 2015.

Patent Filing trend

There was a 22% increase in the patent filing between 2010 and 2011 while subsequent growth has been very low from 2011 to 2013. A quarter analysis of the period 2010-15 shows that there was an increase of 27% in the first quarter in 2010 and 2011. However, there has been a decreasing growth in all of the subsequent quarters, which comes as a bit of surprise.

Residents or Non-Residents, Who are filing more patents?

The office of first filing information gives the ratio of patent filing done by domestic and foreign companies at the German patent office.

Resident Vs Non-resident Filings

During 2010-2015, 80% of the patents filed with the German PTO had German priority and the rest 20% had foreign priority.

We analyzed this 20% data in detail to find the foreign countries that consider Germany – which world’s fourth-largest economy – as a potential market for their inventions.

The German market – which is largest in the EU – due to, however not limited to, its location at the center of Europe, quality engineering, and first-class infrastructure attracts foreign investors in numerous sectors.

The USA filed the most number of patents followed by Japan, South Korea, and China. The US companies were responsible for 40% of the total foreign filing in Germany. Japanese companies filed 27%, South Korean companies 7.8% and Chinese companies’ share was 4.2% in foreign filings at the German PTO.

The yearly patent filing data of the US suggests an annual incremental increase during the period 2011-13. Overall, there was a growth of nearly 37% in the period. The figure for Japan was 37% while South Korea was catching up with 36%.

Since the overall filing has not much increased, the increase in foreign filing implies that resident filing has decreased over the period of time.

The Top IP Law Firms Prosecuting Patents in  Germany

During the period of 2010-2015, 298,000 patents were filed with the German PTO, in which more than 4170 IP law firms were involved.

Out of the total patents, 57,317 patents were filed by non-German companies which were represented by 650+ different law firms. The non-German companies were represented by only 16% of the total law firms of Germany. Other than that, the top 20 law firms prosecuted only 25% of the total foreign patent applications.

The statistics are even more surprising for German companies. The top twenty law firms prosecuted only 9% of the 240,711 patents filed during 2010-15 by German companies. This implies that the patent prosecution in Germany is not concentrated and is widespread.

The chart below represents the top 20 law firms prosecuting patents in Germany.

Prosecution Trend

Manitz, Finsterwald, and Partner prosecuted the highest number of patents followed by Grunecker, Kinkeldey, Stockmair & Schwanhausser. Looking at the yearly filing data, Manitz & Partner prosecuted 205 patents in 2010 as compared with 1190 in 2013 indicating an increase of over 400%. Grunecker, Meissner, and Viering demonstrated an increase of 110%, 116%, and 218%, respectively during the same period.
