【国际讯息】孟加拉国自行车出口稳步上升-转自轮彦自行车快讯当许多其他产品因疫情肆虐而出口下降时，孟加拉国自行车出口却稳步上升。根据孟加拉国出口推广局（EPB）的统计数据显示，2018-2019年度孟加拉国的自行车出口总值为8,400万美元，2019-2020 年度，出口总额为8,260万美元。2020-2021年度的前8个月，出口额已达8,458万美元，同比增长40%。根据欧盟统计局的数据，2017年孟加拉国为英国和欧盟的第三大非欧盟成员自行车进口来源。由于欧洲许多国家的疫情不断升温，导致欧洲市场对自行车的需求持续增加。孟加拉国当地有8家自行车公司，主要以出口为主，其中2家在吉大港出口加工区。其余则分布在达喀尔、Gazipur和Sylhet。Alita公司（BD）早在1995年就在吉大港投资，过去五年出口了80万辆以上的自行车，投产以来累计向欧盟出口约250万辆自行车，价格从每辆60美元到160美元不等。制造原材料中约有30%至40%来自中国、印度、马来西亚、印度尼西亚和越南。各位看官有啥想法？

【国际资讯】SRAM起诉Princeton侵犯其车轮专利权-转载 119hell: 缴纳着专利费用，合理行使专利权利。 SRAM 起诉Princeton Carbon Works侵犯专利权。SRAM声称，Princeton碳轮组上波浪轮圈形状侵犯了其专利的轮圈形状专利，该专利灵感来自于座头鲸鱼鳍。SRAM其产品Zipp 454 Carbon NSW车轮使用了该设计。SRAM指责Princeton侵犯了其专利同时还不断向市场投放侵占专利的产品。SRAM以故意侵权名义控告Princeton以索取三倍的赔偿，并勒令Princeton将未销售的侵权产品销毁。SRAM的律师要求法院立即签发Princeton传票，据悉可能今年年底法院才会批准。 SRAM sues Princeton Carbon Works for patent infringement on aero wheels SRAM claims that PCW is infringing on its patent for a rim shape inspired by a humpback whale flipper. CHICAGO (BRAIN) — SRAM Inc. is suing Princeton Carbon Works, Inc. for patent infringement. SRAM says that the wavy rim shape on Princeton's carbon road wheels infringes on its patent for a rim shape inspired in part by a humpback whale flipper. SRAM uses that design on its Zipp 454 Carbon NSW wheels, which retail for up to $4,000 per pair. SRAM's wheels rely on two patents from inventor Dimitrios Katsanis. The first patent was issued in 2017 and a related patent was issued in 2020. Katsanis assigned both to Metron IP Limited, a Nottingham, UK, company, who in turn assigned them to SRAM. It's not clear when the patent was assigned to SRAM. The patents describe a rim or spokes with an "undulating configuration" that is said to reduce aerodynamic drag, especially in crosswinds. Among the publications cited in the patents is "Hydrodynamic Design of the Humpback Whale Flipper," published in the Journal of Morphology in 1995. Princeton, which entered the market in about 2018, offers wheels with a rim shape that resembles the Zipp design, at least superficially. Princeton says its rim shape is sinusoidal. The Princeton undulations appear symmetric, while the Zipp shape is more like a sawtooth. Many consumer media reviews of the Princeton wheels have remarked on the resemblance. "Princeton CarbonWorks has had a bit of an uphill battle to ensure riders understand there’s a major difference between its sinusoidal rim shape and the biomimicry shape that Zipp touts on its 454 NSW wheels. Aesthetically, the two designs look similar, but according to Princeton, they work vastly differently," a Sept. 2020 review on VeloNews.com began. In a 2018 CyclingTips review, Princeton co-founder Paul Daniels is quoted hinting that he might be open to licensing the design. “It’s in Princeton CarbonWorks’ interest to spend our resources developing next-level product that surpasses our competitors. If we have to pay a royalty along the way because economics dictate that’s a better decision than litigating patent law, then so be it," Daniels said in the article. SRAM's complaint charges that Princeton was aware of SRAM's patent and continued to market its wheels. It's asking for tripled damages for willful infringement and for Princeton to be ordered to deliver up for destruction any remaining inventory. The civil complaint was filed Friday; SRAM's lawyers asked the court to issue a summons for Princeton, which hadn't been granted by the end of the day.A photo of a Princeton Carbon Wheelworks wheel from the SRAM complaint.A drawing from the Katsanis patent that has been assigned to SRAM.
