This IP firm in Essen is one of the best-known litigation outfits in western Germany on the patent attorney side. This is thanks to gradual personnel growth over many years. Over the past year AH has seen stronger growth and appointed a patent attorney from its own ranks to equity partner, as well as hiring a former patent attorney trainee on a permanent contract. These are two important steps for the small, previously cautious firm in preparing for the upcoming generational change in its core area: traditional engineering. The solid ties to many regular clients from the German Mittelstand form the basis for this part of the practice. For companies like Novoferm, Certoplast or Kickert, the firm generally files patents directly as well as conducting opposition suits and infringement proceedings. External lawyers like to call on the patent attorneys in national infringement proceedings for their expertise. The uncertain UPC launch is hardly impacting the firm because of its strong Mittelstand roots, as few suits involving Mittelstand companies are expected.
Patent prosecution with technical expertise in engineering, especially for the automotive and sanitation industry.
