Which elements cannot form the basis of an infringement claim?

• A. Generic unprotectable elements such as common chord progressions.
• B. Original melodies.
• C. Distinctive rhythms.
• D. Harmful lyrical phrases.

Answer: (A)

The concept at work is that an infringement claim can only rest on protecting the actual expression a composer created, not on generic or widely used building blocks. Common chord progressions are standard harmonic devices that appear in countless songs; they’re considered unprotectable because they’re ideas or methods, not original expression fixed in a unique way. Copying a progression alone won’t prove copying of protectable content. In contrast, original melodies are protectable because they embody the creator’s unique musical expression. Distinctive rhythms can also be protectable if they are sufficiently original and distinctive, not just generic beats. Harmful lyrical phrases aren’t themselves a basis for infringement; infringement hinges on copying protectable expression, not on the content being offensive or harmful. So the best answer is that generic unprotectable elements like common chord progressions cannot form the basis of a valid infringement claim, whereas original melodies and distinctive rhythms can.
