More than 50 women who claim they were abused as girls by Mr. Copperman during doctor visits have contacted Kristen Gibbons Feden, of the firm Stradley Ronon in Philadelphia, who is investigating a possible civil suit against Mr. Copperman under the new law. (Ms. Feden prosecuted Bill Cosby for sexual assault.)

Mr. Copperman declined to comment on the allegations. In the past, he has said that he examined the girls in accordance with standard medical practice.

The state medical board, which received repeated complaints over at least 15 years, investigated and revoked his medical license on Dec. 1, 2000. By then, Mr. Copperman was 65 and about to retire.

His accusers see the case as an example of a prominent professional evading accountability despite multiple accusations of sexual abuse.

“Copperman learned he could go on living his life, that the medical degree on his wall outweighed everything we said about what he did,” said Dana Marcus, 56, an administrator of the Victims of Stuart Copperman page on Facebook.

The woman who made the 2000 complaint, now 36, went to the local police precinct with her mother and her sister to file the report.

Her mother had read news reports about the revocation of Mr. Copperman’s license over complaints of sexual abuse by former patients. She told her two daughters, who had also been Mr. Copperman’s patients.
