Question: Chivas 1-2-3 changed its name to Sorcerer on the Rocks to prevent legal fight with which blended Scotch whisky that is part of Pernod Ricard?
Context: Royal Salute is a brand of Scotch whisky produced by Chivas Brothers (owned by Pernod Ricard), founded in 1801 in Aberdeen, Scotland.

Sorcerer on the Rocks (妖術者 オンザロック , Mahotsukai on za Rokkus ) also known as Chivas 1-2-3 (シーバス１-２-３ , Chivas 1-2-3 ) is a spin-off of "Sorcerer Hunters".  The name was changed from Chivas 1-2-3 because ADV Films didn't want to get into a legal fight with the Whiskey company of the same name.  So, the name of the OVAs and the first name of the hero were changed for the English Dub.  The original story is by Satoru Akahori and Miku Yuki, and was published in Media Works' "Monthly Dengeki Comic Gao!"

The particular blend used in Passport Scotch was first produced in the 1960s by master blender Jimmy Lang, of Seagram’s Scottish subsidiary Chivas Brothers, and started being sold in 1965.  The blend recipe for Passport was developed by Chivas Brothers’ blender Jimmy Lang during the 1960s.  It sold 1.7 million bottles in 2015, being a strong performer in Brazil (where it is second on the Scotch whisky market), Angola, Mexico, Spain, Portugal and Poland.

Black Dog is a brand of Scotch Whisky that is distilled, aged and blended in Scotland, and bottled and marketed in India by United Spirits Limited (USL), a subsidiary of Diageo PLC.  In 2013, Black Dog was reported to be the world's fastest growing Scotch Whisky by volume, according to International Wine and Spirits Research (IWSR).  The whiskies used in the blend come from Scotland.  Black Dog Scotch Whisky sold in India is bottled in Parmori District Nasik in Maharashtra, by importing the undiluted spirits from Scotland, a strategy that avoids the import duties imposed on liquor imports to India that are bottled prior to import.  (Import duties may be as high as 150% for liquor bottled prior to import, but only about 30% when bottled in India.)  The brand's main competitors outside the Diageo family are Ballantine’s 12 YO Finest Blended Scotch, 100 Pipers 12 YO Blended Scotch, both owned by Pernod Ricard and two expressions from the Teachers' family, Teacher’s 50, a premium 12 year old Scotch whisky, blended and matured in Scotland but bottled in India starting August 1997 to celebrate India’s 50 years of independence and Teacher's Highland Cream, both owned by Beam Suntory. 100 Pipers is a brand of "standard" blended Scotch whisky with smoked notes that is produced by Pernod Ricard.  The company says it is the "seventh-largest blended Scotch worldwide", the "No. 2 standard whisky in Asia", and the "No. 1 standard whisky" in Thailand.  In addition to Thailand, it is also distributed in India, Spain, and South America.  100 Pipers is a blend of between 25 and 30 source whiskies.  Much of it comes from the Allt a'Bhainne distillery, which is also owned by Pernod Ricard and does not have its own bottling facilities.  100 Pipers is bottled in India and Scotland (and possibly elsewhere).
