  一、欧洲口审意见简介

  口审(Oral proceedings)是欧洲专利审查程序的末端,在欧专局下发的口审通知中通常会规定口审的具体日期、地点以及形式(现场会晤或视频会议),还会规定递交书面答复意见(written submissions)的期限。口审通知的发文日距口审举行日期的时间跨度通常为至少四个月。

  口审意见答复通常分为两个阶段:第一阶段,递交书面答复意见(可以包括申请文件修改以及争辩);第二阶段,在书面答复意见仍然不被审查员接受、申请不能获得授权的情况下,在口审通知规定的时间以现场会晤或视频会议的形式与审查员举行口审(如果递交书面答复意见之后获得了授权,就不再举行第二阶段的口审)。

  在提供针对口审的书面答复意见时,允许提供两种答复方案,其中一个方案作为主请求(main request),另一个方案作为辅请求(auxiliary request)。

  去口审举办地参加现场口审,需要支付外所律师的代理费、交通费、食宿费等,因此口审的费用比较高,通常为普通OA费用的3-4倍。如果本申请的授权前景黯淡,代理人在向客户提供答复建议时,需要提醒客户是否有必要参加口审,以避免产生不必要的高额费用。

 

  二、口审案例分享

  1.审查意见

  笔者曾处理过关于欧洲申请EP16869830.6的口审意见,该口审的发文日为2020年9月11日,递交书面答复意见的期限为2020年12月23日,口审的举办日期为2021年1月26日,形式为视频会议。

  在审查意见中,审查员认为上一通答复稿中修改后的权1仍然存在不清楚和缺乏创造性的问题。

  关于不清楚,审查员认为,根据权1,多个正极耳和多个负极耳形成极耳叠合结构或极耳错开排列结构;根据权2(权1的从权),锂离子电池电芯包括形成极耳叠合结构的多个正极耳,权2对负极耳的设置没有进行限定,因此多个负极耳可以为叠合的或错开排列的,即权2对应于如下实施例:正极耳形成极耳叠合结构,负极耳可以为叠合的或错开排列的;根据权3(权2的从权),进一步限定锂离子电池电芯包括形成极耳叠合结构的多个负极耳,因此,权1+权2+权3限定了包括多个正极耳和多个负极耳的锂离子电池电芯,其中,正极耳和负极耳均形成极耳叠合结构;根据权4(权3的从权),限定了多个正极耳或多个负极耳形成极耳错开排列结构。权4+权3限定了多个正极耳同时形成了极耳叠合结构和极耳错开排列结构,且多个负极耳同时形成了极耳叠合结构和极耳错开排列结构。说明书没有与权4的技术方案对应的实施例。此外,本申请说明书第54段有以下记载:通过以上公式计算出极耳的位置后,极耳向前向后移动一定的距离以形成极耳错开排列结构。这意味着,根据说明书,极耳叠合结构和极耳错开排列结构是选择关系,不是同时形成的。因此,权4不应是权1至权3的从权。

  关于创造性,审查员认为权1中关于极耳间距离的限定公式未被对比文件公开,权1具有新颖性。但是,具有特定距离的极耳叠合结构或极耳错开排列结构是现有技术中的电池结构的显而易见的替代方案,没有产生相关的有益效果,因此,权1不具有创造性。

  2.答复思路

  关于权1同时记载关于极耳叠合结构和极耳错开排列结构导致的不清楚的问题,经与发明人沟通,极耳叠合结构和极耳错开排列结构是选择关系,不可能同时形成。为了克服不清楚的问题,笔者建议对权项重新进行撰写,将权1中的并列方案进行拆分,撰写一套关于极耳叠合结构的权项,正极耳间的距离通过d1=n1w-x1+(0.5πt∑n1-0.5πt)或d1=n3w+x1+[0.5πt∑(n3+1)-0.5πt]进行限定;此外,撰写一套关于极耳错开排列结构的权项,正极耳间的距离通过d1=n1w-x1+(0.5πt∑n1-0.5πt)或d1=n3w+x1+[0.5πt∑(n3+1)−0.5πt]进行限定。

  拆分后的独权1(极耳叠合结构)和独权6(极耳错开排列结构)如下:

  1. A lithium-ion battery cell, comprising:

  a positive plate;

  a membrane; and

  a negative plate, wherein

  a plurality of positive lugs is arranged along a winding direction on the positive plate in a unfolded state, a plurality of negative lugs is arranged along the winding direction on the negative plate in a unfolded state, and

  the positive plate and the negative plate are separated by the membrane and are wound to form the lithium-ion battery cell, the plurality of positive lugs forms a lug laminated structure, and the plurality of negative lugs forms a lug laminated structure,

  and wherein the plurality of positive lugs is arranged in parallel in a direction along a length of the positive plate;

  a first lug margin x1 indicates a distance between a first positive lug and a head of the positive plate relative to the winding direction, a distance between each of the positive lugs other than the first positive lug and the head of the positive plate is indicated by d1, with d1=n1w-x1+(0.5πt∑n1-0.5πt) or d1=n3w+x1+[0.5πt∑(n3+1)-0.5πt];

  the lithium-ion battery cell is square, and the plurality of positive lugs forms the lug laminated structure;

  where t indicates a sum of thicknesses of the positive plate, the membrane and the negative plate, w indicates a width of the cell, the first positive lug is the one of the positive lugs which is located closest to the head of the positive plate, n1 indicates that a positive lug is located at the n1-th w on the positive plate along a direction from the head to a tail of the positive plate, and n3 indicates that a positive lug is located at the (n3+1)-th w on the positive plate along the direction from the head to the tail of the positive plate.

  6. A lithium-ion battery cell, comprising:

  a positive plate;

  a membrane; and

  a negative plate, wherein

  a plurality of positive lugs is arranged along a winding direction on the positive plate in a unfolded state, a plurality of negative lugs is arranged along the winding direction on the negative plate in unfolded state, and

  the positive plate and the negative plate are separated by the membrane and are wound to form the lithium-ion battery cell, the plurality of positive lugs forms a lug staggered structure, and the plurality of negative lugs forms a lug staggered structure;

  wherein

  wherein intervals between adjacent staggered positive lugs in m1 positive lugs are the same; starting from the first one in the m1 positive lugs, d1 of the m1 positive lugs is decreased by a first interval value mq; wherein d1=n1w-x1+(0.5πt∑n1-0.5πt), q indicates an interval between two adjacent staggered positive lugs, m indicates a sequence number of a positive lug in the m1 positive lugs along a direction from the head to the tail of the positive plate, 1≤m≤m1; or

  starting from the first one in the m1 positive lugs, d1 of each of the m1 positive lugs is increased by a first interval value mq; wherein d1=n3w+x1+[0.5πt∑(n3+1)−0.5πt], q indicates an interval between two adjacent staggered positive lugs, m indicates a sequence number of a positive lug in the m1 positive lugs along a direction from the head to tail of the positive plate 1≤m≤m1.

  关于独权缺乏创造性的问题,与口审之前的OA答复中的策略相似。争辩权1和(权6)中记载的极耳间的距离公式d1未被现有技术公开,说明权1中限定的极耳设置方式不是本领域的惯用技术手段或公知常识;该区别技术特征所解决的技术问题为如何通过设置电池电芯中的极耳之间的间距以提高电池的倍率性能(即电池功率密度)。相较于之前的答复,对技术问题进行了特别的具体化,使技术问题与区别技术特征之间建立了紧密的对应关系。

  3.答复结果

  笔者根据上述答复思路进行答复之后,审查员下发了授权通知,没有进行视频会议形式的口审。

     

  4.案例总结

  针对题述口审意见在递交书面答复意见之后直接获得了授权,避免了以视频会议形式进行的口审,为申请人节省了费用。针对审查员指出的不清楚的审查意见,笔者经与发明人沟通后将原权1的并列技术方案拆分为两个独权,较为彻底地解决了不清楚的问题;不清楚的问题解决之后,审查员对技术方案的理解更深入,也接受了关于创造性的争辩(其实创造性的争辩理由与之前的OA答复比较相似)。
