Dr. Jaenichen's activities are primarily in the biotech and pharmaceutical area. He has frequently lectured internationally, has chaired numerous conferences and has authored many publications on biotech intellectual property. The sixth edition of his book “From Clones to Claims” on the European Patent Office's jurisdiction in the field of biotechnology in comparison to the US and Japanese practice was published together with Jürgen Meier, James F. Haley, Leslie McDonell and Yoshinori Hosoda in January 2016.

Dr. Jaenichen represents his clients at the EPO, the GPTO and before German courts. He specializes in prosecution, oppositions, revocation proceedings, infringement proceedings and compulsory license proceedings in biotechnology and on pharmaceutical inventions. He is also experienced in the strategic creation and structuring of patent portfolios.

He has handled cases in the entire field of biotechnology, biology, including microbiology and molecular biology, genetics, clinical sciences and plant genetics. Examples relate to cloned genes, the production of recombinant proteins, including their tailored glycosylation, various kinds of antibodies (monoclonal, single chain, humanized, recombinant, Herceptin, Rituximab, Golimumab, Belimumab, anti-PD1-antibodies, anti-CD27-antibodies, anti-TNF-antibodies, etc.), nucleic acid amplification processes, RNAi, aptamers, ribozymes, antisense RNA, CRISPR, DNA polymerases, transgenic plants and animals, vaccines, recombinant viruses, syntheses of non-ribosomal antibiotics, biological implants, gene therapy, enzyme replacement therapy, companion diagnostics and many more.

Furthermore, together with the chemistry department, he deals with pharmaceutical and pharmacological inventions with respect to classic chemical active ingredients and also recombinant agents, sometimes identified by means of combinatorial chemistry or high throughput screenings. The department has extensive experience in the registration and enforcement of Supplementary Protection Certificates (SPCs).

He was involved in infringement litigation concerning several DNA molecules, several enzymes, antibodies of different kinds against different targets, recombinant proteins, bisphosphonates and medical uses of the mentioned molecules.
