Excerpt from The Grant and Validity of British Patents for Inventions Abstracts of Cases will render it useful to practising lawyers. It has been ascertained by an official inquiry that of the Patents for Inventions granted in England no fewer than 42 per cent., that is, about 5780 per annum, are invalid on the ground of having been already patented in this country. An examination of the results of litigation shows that, of such patents as are commercially worth infringing, no less than 51 per cent. Are invalid. The invalidity of these patents is in many cases not discovered till after the lapse of years but, even assuming that no invalid patent is renewed, sums amounting to 2 per annum are paid for patents which give no legal protection to the patentees. This state of affairs brings discredit upon all British patents, and diminishes the market value even of those which are valid. Although the new procedure shortly to be brought into operation will prevent the grant of a large proportion of bad patents, many will still exist, as it deals only with one cause of invalidity.
