DECLARE @brands TABLE (brand NVARCHAR(50));
 
INSERT INTO @brands (brand)
VALUES ('BF Goodrich');

SELECT *
FROM dbo.productOwners
INNER JOIN @brands ON 
	REPLACE(LOWER(brand), ' ', '') = REPLACE(LOWER(productOwner_name), ' ', '') OR 
	REPLACE(LOWER(productOwner_name), ' ', '') = CONCAT(REPLACE(LOWER(brand), ' ', ''),'®')

Correctly returns a single row when there is an existing row in the dbo.productOwners table with the productOwner_name value set to "BFGoodrich®"
