English to Arabic Tech/Engineering Patents

• Regarding claim 2 citing claim 1, D1 discloses a convex portion of the convex connecting conductor (see figure 2) corresponding to the step portion of claim 1. D1 does not explicitly disclose the ring member and a silver-plated layer. However, D2 discloses a contactor having an outer peripheral member which is fitted to the outer periphery of a central base member and formed from silver or silver alloy by a cold spray method (see paragraphs [0004], [0033], [0040] and figures 1, 6) and D3 discloses a main conductor having a hollow shape and an inserting end portion having a step formed at the end thereof (see figure 2). Technical field of D1, D2 and D3 is same and claim 2 does not include any additional feature with a technical effect. Accordingly, it is obvious to a person skilled in the art to combine D1 with D2 and D3. Therefore, the subject matter of claim 2 lacks inventive step as being obvious in view of D1, D2 and D3.
