Patent No. EP3688157 (titled "High Efficiency Targeted In Situ Genome-Wide Profiling") was filed by Fred Hutchinson Cancer Center on Sep 25, 2018. The application was issued on Apr 27, 2022.
A method for chromatin profiling that enables the detection of protein-DNA interactions without the need for chromatin immunoprecipitation (ChIP). The method, called CUT&RUN, involves targeting a specific protein of interest with an antibody coupled to a transposase, which then cleaves the surrounding chromatin. The resulting DNA fragments are released into solution and can be sequenced to determine the protein's binding sites. CUT&RUN offers improved specificity and sensitivity compared to traditional ChIP methods, particularly when performed on magnetic beads, and enables the analysis of low-input samples.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
