The protest movement has raised awareness about the gay-rights situation in Russia and has boosted hopes among activists that the International Olympic Committee will be more attentive to human rights issues in selecting future Olympic hosts.
Nonetheless, activists acknowledge some frustration that the law remains in place spared direct criticism by some of the Olympic movement's major players.
Both Human Rights Watch and the Human Rights Campaign have written to all of the Worldwide Olympics Partners, urging the corporations to call for repeal of the Russian law.
To date, according to the two rights groups, none of the companies has taken that step, though several have expressed general support for human rights and promoted their own nondiscrimination employment policies. There are 10 Worldwide Partners in all including General Electric, Procter & Gamble, Dow Chemical, Omega, Panasonic, Samsung and the French-based technology company Atos.
"The responses failed to recognize that their brands are propping up an event that will go down in history as the anti-gay games," said Fred Sainz of the Human Rights Campaign, the largest U.S. gay-rights group.
Activist leaders say there is little interest at this stage in proposing formal boycotts of the corporate sponsors, but they hope to find other ways to intensify the pressure. Some activists have suggested a new wave of protests as the games begin in February, targeting Russian diplomatic missions and the corporate sponsors' offices.
"No one is prepared to back down," said Andre Banks of AllOut, one of the protest groups. "Consumers will hold these companies responsible."
Human Rights Watch made available to The Associated Press the letters sent by several of the corporations in response to its requests. In general, the letters and separate statements sent by the sponsors to the AP conveyed the companies' disapproval of any form of discrimination and cited assurances provided by Russian authorities to the IOC that everyone would be welcome at the Winter Games regardless of sexual orientation.
"There's no room for discrimination under the Golden Arches," said a statement from McDonald's. "We support the IOC's belief that sport is a human right and the Olympic Games should be open to all, free of discrimination."
Visa provided a similar statement to the AP.
Coca-Cola, the target of recent gay-rights protests in Atlanta and New York City, noted that its employment practices had earned praise from the Human Rights Campaign over many years.
"We do not condone intolerance or discrimination of any kind anywhere in the world," it said.
Protest leaders said those practices did not excuse any reluctance to speak out against the Russian law and to take a stand on human rights in Russia beyond the Olympic context.
"You can't support gays and lesbians in one country, then stay silent on the issues in the places where gays and lesbians need vocal, powerful allies the most," said Andre Banks.
In an early phase of the protest campaign, activists called for a boycott of Stolichnaya vodka. The CEO of the company that produces Stolichnaya subsequently criticized the anti-gay law and said his firm had no ties to the Russian government.
Among gay-rights activists in Russia, there have been mixed views of the protests unfolding in the U.S. and Western Europe.
"These boycotts and protests have not made any gains for the Russian LGBT community and won't in the future," said Nikolai Alexeyev, a pioneer of Russia's gay-pride movement. "I believe that a lot of people in the West have been doing PR for themselves using Russian issues."
He suggested that Western governments ban entry to any Russian politician involved in passing the anti-gay law.
