The word “substantially” is a relative term and should be interpreted in accordance with the context of claim in which it is used. Moss v. Patterson Ballagh Corp. D.C.Cal., 80 P.Supp. C10, 637.
“Substantial” is a relative term, the meaning of which is to be gauged by all the circumstances surrounding the transaction, in reference to which the expression has been used. It imports a considerable amount or value in opposition to that which is inconsequential or small.
