工业4.0背景下德国应对3D打印技术的法政策学分析——兼论我国对3D打印技术的法政策路径选择

3D打印技术作为工业4.0中实现"智能生产"和"智能工厂"的方式,是促进我国制造业转型的重要路径。通过对德国政府应对3D打印技术发展所制订的科技政策和法律政策的分析,欲促进我国3D打印技术快速发展,提升我国3D打印产业的国际竞争力,首先,应通过制定和完善与3D打印有关的科技政策,引导科研资源和资本向3D打印产业分流;其次,应通过对现行相关法律的解释、归纳和演绎,寻求应对3D打印技术发展的法律适用的空间;此外,在政策的制定与法律适用的过程中,需要选择符合我国国情的3D打印技术保护标准和创新发展之路径。     

3D打印技术发展与专利法回应

3D打印技术在改变制造业基础设施的配置、原材料的供应链和产品销售模式的同时,也对现行专利法律制度形成了冲击和挑战。在3D打印技术领域,如何在激励创新与防止潜在的非法复制之间实现平衡,廓清合法的"修理"和不合法的"再造"之间的界限以及以"非生产经营目的"的个人打印是否构成侵权等问题亟待专利法律制度的回应。面对3D打印技术带来的机遇与挑战,立法者应重新审视《专利法》的制度基础,在平衡技术革新和其他社会、经济价值的基础上,推动3D打印技术和专利法律制度间的互动演进式发展。     

Technical Note: Analyzing the effect of repeated fusing on toner to examine printing alterations made by the same laser printer

With continuous innovations in laser printing technology, the number of cases of falsification using laser printers is increasing annually. Difficulties in identifying printing alternations, especially laser-printed alternations by the same printer are increasing. Effectively, repeated printing on the same page by the same printer means the original toner on the document was fused repeatedly. Thus, this study mainly investigates the effects of second fusing on the microscopic morphology of toner to examine whether documents have been tampered with. To detect the influence of fusing on the microscopic morphology of toner, 170 documents printed by 17 different models of laser printers from 5 brands were studied. It was found that, according to microscopic observations, the micrographs of toner may become brighter, darker or both with repetition of the fusing process. By calculating the average gray value of the micrographs of toner, it was found that, in some laser printers, the gray value of the thermoplastic accumulation area will increase after a second fusing, and the gray value of the toner particle dispersion area will decrease. In conclusion, by comparing the micrographs of toner from suspicious and reliable contents on the same page or in the same document, together with the measurement and analysis of average gray values, it is possible to examine the once- and twice-fused document contents, and further determine whether the document has been altered.     

Merging with the metals: an analysis of the role micro-political relationships played in the merger of the Printing and Kindred Industries Union with the Australian Manufacturing Workers Union

ABSTRACT

In the spring of 1987, the Printing and Kindred Industries Union (PKIU), Federal Executive Committee, reluctantly concluded that membership decline and the resultant fall in income meant that the union needed to find an amalgamation partner. In common with many Australian unions, which felt similarly compelled to merge, there was initially a lack of consensus over a preferred merger partner. In most other unions these disagreements were eventually resolved, an amalgamation deal negotiated, and membership endorsement of the merger secured. This was not the case in the PKIU. Instead the union remained in intense internal conflict, throughout the seven-year amalgamation process. Scholars have suggested that the PKIU’s amalgamation fissures were caused by political, economic, industrial and institutional disagreements. Other authors have gone further and argue that dramatic shifts in the PKIU’s and other unions amalgamation policies, during the 1980s and 1990s, were the result of alterations in the strengths of different internal political factions, or the rejection of a union’s merger policy by the membership. This article, while accepting that political, economic, industrial and institutional factors all influenced the PKIU’s internal debate, puts forward an alternative hypothesis. It asserts that micro-political factors, specifically personal animosities, friendships and loyalties, played a significant role in determining the eventual choice of an amalgamation partner, and the contrasting results of its two merger ballots.     

基于过程解析法的同机添加打印文件鉴别方法

利用喷墨打印机二次添加打印,特别是同机添加打印变造文件,是文件检验工作中的难题。喷墨打印机采用串行接字方式,内部结构复杂,喷嘴数目多,同一型号打印机又有多种质量模式。因此,在打印图文上往往留有较多的打印特征,如对接重叠线、对接错位线、横向白线、卫星墨点、墨点错位等。分析爱普生、惠普、佳能三个品牌的20台喷墨打印机不同质量模式的打印文件,发现这些特征重复再现频率较高,不同台打印机打印文件特征差异较大,同一台打印机在不同质量模式下特征出现的位置也不尽相同。通过提取打印文件上的打印特征,分析字车运行方向和打印图文pass数值,分解打印过程并制作检验图谱,判断打印文件的可疑区域是否符合打印规律,为确定二次添加打印提供帮助,提升检验过程的规范性、检验意见的准确性和结果依据的可读性。     

3D打印冲击下专利间接侵权制度研究

近20多年来,3D打印技术的迅猛发展及其打印成本的不断下降,使其渐渐开始融入到人们的日常生活之中。在网络时代背景下,3D数据文件作为侵权客体的"关键部件",能够通过网络共享迅速地传播,将给现有的专利侵权制度带来一场变革。3D打印模式下专利侵权呈现出"版权化"趋势,使现有专利侵权制度中共同侵权的实用性严重"萎缩",而借鉴帮助侵权、代位侵权也并非长远之计。所以,面对专利侵权"新模式",归根结底还是专利间接侵权制度的构建问题。与此同时,借鉴美国《数字千年版权法》也是应对冲击的策略之一。
