Whether the Penmen posters contained protectable expression beyond unprotected ideas, common anatomy, everyday activities, and natural poses.
Holding
Yes. The Penmen contained some protectable original expression, although Blehm could not claim exclusive rights over the general ideas embodied in the figures.
Reasoning
Copyright protects an author’s original expression, not ideas, concepts, or features that belong to the public domain. Thus, Blehm could not monopolize the ideas of cartoon people, figures with arms and legs, large smiles, or figures performing familiar activities such as skateboarding, catching a Frisbee, holding a birthday cake, or making a peace sign.
The court also excluded poses that naturally follow from an activity. A figure reclining in a bath, lounging in an inner tube, or assuming a pose associated with catching a Frisbee reflects an unprotected idea or functional depiction of the activity, rather than Blehm’s exclusive expression of it.
Still, the court rejected any suggestion that the Penmen were merely unprotectable stick figures. Blehm made particular stylistic choices: black-filled heads with white half-moon shapes, the omission of ordinary facial features, detached hovering heads, relatively short torsos, long thin limbs, four fingers, unusually large feet, and a consistent visual style governed by his own drawing rules. Those choices supplied the minimal creativity needed for copyright protection.
