Company patents

Nippon Pillar Packing Co., Ltd.

Nippon Pillar Packing Co., Ltd. demonstrates a surprising shift in its patent strategy, with a strong emerging focus on "Pumps (Positive Displacement)" showing a remarkable +300.0% year-over-year growth in 2026 (so far), despite it representing only 13.4% of their total portfolio. This contrasts with their historically dominant "Pipes & Tubing" category, which, while still 40.3% of their portfolio, has seen a significant decline of -80.0% in 2025 and -33.3% so far in 2026, indicating a shifting priority away from this core area.
