I love my 1903A3s.
The extent of the Mauser patent issues used on the 1903 Springfield
467180 , Shell Extractor 20 cents per arm
477671, Shell Extractor & Collar 5cents per each arm.
482376, Clips, (called cartridge holder for magazine guns) 50 cents per thousand clips
527869, Oct, 1894 , Magazine 25 Cents per each arm.
547932, Clip (called cartridge pack) 50 cents per thousand clips.
547933, Safety, covered by 590271
590271, Sept, 1897 25 cents per each arm
Otherwise the 1903 is not a patent ripoff of the 1898 Mauser.
My .02
BTW - the Spaniards used the 7x57 Model 1893 Mauser in the Spanish-American War, not the Model 1898 as the author claims.
