Prosecutors have asked Justice James M. Burke to consider 36 “prior bad acts” when determining his sentence. Those include alleged sexual assaults against women spanning four decades for which Mr. Weinstein was never criminally charged. The earliest allegation comes from woman who says he raped her on a business trip in 1978.

But Mr. Weinstein’s lawyers have argued in court papers that the allegations were never proven and should not be used to determine his punishment.

They also stressed that the producer was acquitted of the most serious charges against him: one count of first-degree rape, which requires the use of force, and two counts of predatory sexual assault, which requires the state to prove he committed serious sexual felonies against at least two women.

The defense lawyers have requested a prison term of five years, the least the law allows. Noting that the life expectancy of someone Mr. Weinstein’s age is about 12 years, they argued a longer term than five years “is likely to constitute a de facto life sentence.”

In all, six women testified about their sexual encounters with Mr. Weinstein during his trial in the State Supreme Court in Manhattan.

The jury found Mr. Weinstein guilty of forcibly performing oral sex on a production assistant, Miriam Haley, in his Manhattan loft in 2006, and of raping an aspiring actress, Jessica Mann, at a Midtown Manhattan hotel in 2013.

On the advice of his lawyers, Mr. Weinstein did not testify. The newly released court documents provided one possible reason that he opted not to take the stand. Manhattan prosecutors were prepared to call 11 more “prior bad act” witnesses to testify if he had.
