The Supreme Court reasoned that laws of

the statutory categories because those
categories embrace &quot;the basic tools of
scientific and technological work.&quot;

S.Ct. 253, 34 L.Ed.2d 273 (1972).

The Supreme Court did not presume to
provide a rigid formula or definition for

at 3236 (The Court has &quot;never

invited this court to develop &quot;other limiting
