Abstract
Abstract A method and apparatus are disclosed for automatically finding and classifying any group of trademarks belonging to an initial series and having similarities with groups of trademarks of another series. The classification is arranged in increasing or decreasing order according to the risks of conflict involved in these similarities. The analysis of the similarities provides an indication of the likelihood of confusion between trademarks which are proposed to be registered and those already registered. The apparatus includes a memory for storing the first and second groupings of trademarks. The groupings are then analyzed in pairs by a comparing and counting device which determines for each pair the numbers of the shortest and longest groupings, the longest sequence of common signs to both groupings, the number of signs common to both groupings other than those in the sequence and the number of signs of the longest groupings not found in the other grouping. These various quantities are then used to compute a coefficient of simularity which is in turn used to compute the evaluation of the risk of conflict. The computed risks of conflict exceeding a predetermined value are classified in ascending or descending order and printed for final evaluation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
270 words
An apparatus for automatically finding and classifying trade marks or similar distinguishing signs MC of a first series representing marks previously registered and which have similarities capable of involving a risk of conflict R with trade marks or similar distinguishing signs MP of a second series representing marks presented for registration or use, said series of trade marks MC and MP each being represented by groupings of letters, comprising: a. first memory means for recording said MC and MP groupings, b. comparing and counting means for analyzing, pair by pair, each pair comprising an MCi grouping and an MPj grouping to determine for each pair, the number l of the letters in the shortest trade mark, the number L of the letters in the longest trade mark, the number a of letters of the longest continuous or discontinuous sequence common to both groupings and disposed in the same relative positions within the sequence, the number b of letters common to both groupings other than those of the longest sequence, the number c of letters of the longest grouping not found in the other grouping, c. second memory means for storing predetermined values of the functions A(a, l), B(b,L) and C(c,L) having increasing slopes for increasing values of a, b and c, respectively, for l and L constant, and d. adding means connected to receive from said second memory means the values Aij, Bij and Cij corresponding to the numbers l, L, a, b, and c determined by said comparing and counting means for determining a coefficient of similarity (Aij + Bij - Cij) proportional to said risk of conflict R.
Claim 2
Independent Claim
