Dolby International AB vs Optoma - UPC Case on Access to Documents

In this legal decision, the Local Chamber of Düsseldorf dealt with a request for file inspection filed by an attorney interested in accessing the case records of Dolby International AB against Optoma entities concerning a patent EP 3 605 534. The main proceedings were concluded earlier with the withdrawal of the lawsuit by the plaintiff and acceptance by the defendants. The applicant, a lawyer, sought access to the records for professional interest related to FRAND issues in audio coding. However, the court partially denied full access due to confidentiality concerns and the potential impact on ongoing parallel proceedings. The court ruled that certain documents, especially those containing confidential negotiation details, should be redacted or remain inaccessible to protect the integrity of proceedings. The request was rejected, particularly in relation to confidential sections.
