slide 案例1 slide 案例1 案情说明：审查员在一通中指出：CN1432648A (D1)公开权利要求的前部分内容，CN1270953A (D2)公开使用刮膜短程蒸馏装置来精制乳酸。 申请人强调： 申请人修改了权利要求1，导致对比文件2不宜使用。 slide 案例1 重点针对两次分离步骤即“刮膜(式/型)蒸发器”和“短程蒸馏”进行检索。 1 210 刮膜 (WIPED prox/distance 2 FILM ) 2 1127 短程 (SHORT prox/distance 3 PATH) 3 23篇 1*2 (1 AND 2) 4 15 酸*3 尝试用“酸” （ACID? AND 3） 发明点的关键词比较准确地把握，而对于其它关键词则是上、下位概念多种尝试。 slide 案例1 经过浏览发现以下相关文献： PN - WO0138283 A1DW200153 CN1399623 A DW200337 AB - NOVELTY : Purification of an aqueous solution of an organic acid involves subjecting the solution to at least two distillation steps. … In the first distillation step, the solution is brought into the vapor phase by film evaporation and the vapor is passed to a first distillation column. …The second distillation is carried out in at least one short path distillation evaporator and/or vacuum distillation unit (preferably vacuum distillation units). …The film evaporation device is a wiped film, a thin film and/or a falling film evaporation device. slide 案例2 200780034569.8 [权利要求1] 一种光学材料用树脂的制造方法，所述制造方法将包含多硫醇化合物和多异（硫）氰酸酯化合物的聚合性组合物进行聚合，其特征在于，水分含量为１０～３００ｐｐｍ。 slide 案例2 判断发明点：水含量和水分含量 1 103269(篇) (水+水分)*含量 发明点 (MOISTURE OR WATER OR H2O) prox/unit = sentence (CONTENT? OR CONT.) 2 641 ( (聚)硫醇+(多)硫醇+巯基)*(多异硫氰酸酯+多异氰酸酯+(异*硫*氰酸酯)) (POLYTHIOL? OR MERCAPTO) AND (POLYISOTHIOCYANATE OR POLYISOCYANATE OR (POLYISO prox/distance 1 THIO prox/distance 1 CYANATE)) 3 10 1*2 (1 AND 2 ) 4 5032 透镜 (LENS? ) 5 3 4*3 (4 AND 3 ) slide 案例2 经过浏览，发现以下相关文献： PN - JP2006162926 A DW200833 - DETAILED DESCRIPTION : Component (A) containing aromatic polyisocyanate compound(s), aliphatic polyisocyanate compound(s) or alicyclic
