2.3 Restrictions to file inspection

Subsequent to the publication of the European patent application any person may inspect and obtain information from the files. Inspection of files and communication of information are subject to the restrictions laid down in Rule 144 (see A‑XI, 2.1). If it is decided that certain papers marked "confidential" are not to be excluded from file inspection under Rule 144, they are returned to the sender (see T 516/89).
