[Analysis of test questions]: This question examines the knowledge points of patent rights in intellectual property rights. Patented inventions and creations are intangible intellectual and creative achievements, which are not as intuitive as tangible property. They must be examined and determined by the competent patent authority in accordance with legal procedures. Before approval, any inventions and creations cannot become patents.
Where two or more applicants apply for a patent for the same invention-creation respectively, the patent right shall be granted to the applicant who files first. Article 41 of the Detailed Rules for the Implementation of the Patent Law of the People's Republic of China (revised in 2010): Where two or more applicants apply for a patent for the same invention-creation on the same day (referring to the filing date; if there is priority, referring to the priority date), they shall After receiving the notice from the patent administrative department of the State Council, the applicant will be determined through negotiation. In short, the principle of applying for a patent right is: whoever applies first gets it, and the application is negotiated and determined at the same time.

【试题解析】∶有合同约定，著作权归委托方，那么就归属委托方;而在合同中未约定著作权归属，归创作方。
对于题干描述说明未签订书面合同，则该著作权归创作方，(X公司接受Y公司的委托)，即创作方X公司。

- A. 《计算机软件保护条例》和《软件法》
- B. 《中华人民共和国著作权法》和《计算机软件保护条例》
- C. 《中华人民共和国著作权法》和《软件法》
- D. 《中华人民共和国版权法》和《中华人民共和国著作权法》
【试题解析】∶对于软件著作权和软件作品受到《中华人民共和国著作权法》和《计算机软件保护条例》两个文件的保护。

- A. 该软件属于委托单位
- B. 若该单位与李某对软件的归属有特别的约定，则遵从约定;无约定的，原则上归属于李某
- C. 取决于该软件是否属于单位分派给李某的
- D. 无论李某与该单位有无特别约定，该软件属于李某
【试题解析】∶根据题干描述，这里不能排除职务作品，对于A选项和B选项来看，B选项更严谨，因此，本题选择B选项。
以下有关计算机软件著作权的叙述中，正确的是（）。
- A. 非法进行拷贝、发布或更改软件的人被称为软件盗版者
- B. 《计算机软件保护条例》是国家知识产权局颁布的，用来保护软件著作权人的权益
- C. 软件著作权属于软件开发者，软件著作权自软件开发完成之日起产生
- D. 用户购买了具有版权的软件，则具有对该软件的使用权和复制权
【试题解析】∶选项B中由国务院颁布；选项C中委托开发、合作开发软件著作权的归属及行使原则与一般作品著作权归属及行使原则一样，但职务计算机软件的著作权归属有一定的特殊性。自然人在法人或者其他组织中任职期间所开发的软件有下列情形之一的，该软件著作权由该法人或者其他组织享有，该法人或者其他组织可以对开发软件的自然人进行奖励;选项中复制权，是指制作作品复制品的权利。依作品表现形式不同分为三种情形：（1）以图书、报纸、期刊等印刷品形式复制和传播作品的权利，即通常所说的出版权；（2）以唱片、磁带、k月片寺音像制品形式复制和传播作品的权利，即录音录像权或机械复制权；（3）使用临摹、照相、雕塑、雕刻等方法复制和传播美术等作品的权利，即狭义上的复制权。
为说明某一问题，在学术论文中需要引用某些资料。以下叙述中，(）是不正确的。
- A. 既可引用发表的作品，也可引用未发表的作品
- B. 只能限于介绍、评论作品
- C. 只要不构成自己作品的主要部分，可适当引用资料
- D. 不必征得原作者的同意，不需要向他支付报酬
【试题解析】∶根据《著作权法》的规定，符合法定许可条件的都是已发表作品"，由此推知，引用未发表作品，必须征得作者同意，因为这涉及到作者的发表权问题。
合理使用是不必征得原作者的同意，不需要向他支付报酬，其使用的范围和具体方式，具体而言可以从以下几个方面理解：
(1）引用的目的是为了介绍、评论某一作品或者说明某一问题。
(2）引用的比例必须适当。一般说来，引用不应当比评论、介绍或者说明还长。
(3）引用的作品必须是已经发表的作品。
(4）引用他人的作品，应当指明作者的姓名，作品的名称，并且不得侵犯著作权人按照著作权法享有的其他权利。
李某在《电脑与编程》杂志上看到张某发表的一组程序，颇为欣赏，就复印了一百份作为程序设计辅导材料发给了学生。李某又将这组程序逐段加X评析，写成评论文章后投到《电脑编程技巧》杂志上发表。李某的行为（）。
- A. 侵犯了张某的著作权，因为其未经许可，擅自复印张某的程序
- B. 侵犯了张某的著作权，因为在评论文章中全文引用了发表的程序
- C. 不侵犯张某的著作权，其行为属于合理使用
- D. 侵犯了张某的著作权，因为其擅自复印，又在其发表的文章中全文引用了张某的程序
【试题解析】∶《中华人民共和国著作权法》第十二条规定:"改编、翻译、注释、整理已有作品而产生的作品。其著作权由改编、翻译、注释、整理人享有，但行使著作权时，不得侵犯原作品的著作权。"根据一件己有的作品，利用改编、翻译、注释、整理等演绎方式而创作的掇生作品称之为演绎作品。演绎是一种创作，因而演绎作品是一种新创作的作品。
演绎作者对其演绎作品享有完整的著作权。本题中李某将《电脑与编程》杂志上看到张某发表的一组程序逐段加以评析，写成评论文章后投到《电脑编程技巧》杂志上发表，故李某的“评论文章"属于演绎作品，其行为不侵犯张某的著作权，其行为属于合理使用。
下列智力成果中，能取得专利权的是（）。
- A. 计算机程序代码
- B. 游戏的规则和方法
- C. 计算机算法
- D. 用于控制测试过程的程序
【试题解析】∶专利法明确规定，智力活动的规则和方法不取得专利权。智力活动规则和方法是直接作用于人的思维，与产业生产中的技术活动不发生直接关系，并不是对自然规律的利用，不属于技术方案。通常，智力活动规则和方法是一些人为的规则，如管理规则、游戏规则、统计方法、分类方法和计算方法等。
算法被认为是一种数学公式，反映的是自然法则和逻辑思维过程，属于智力活动规则和方法，不能受到专利法的保护。算法对于计算机软件而言极其重要，是计算机程序的基础，计算机软件总是离不开算法。因此，计算机软件本身属于智力活动规则和方法的范畴，不能够授予专利权。无论是源程序还是目标程序，它体现的是智力活动的规则和方法。因此仅以单纯的计算机程序为主题的发明创造是不能获得专利权的。
随着计算机技术的发展，不能授予专利权的智力活动规则和方法与能够授予专利权的方法之间的界线比较模糊了。例如，抽象出一种生产过程的数学模式，设计一种算法，通过予以运行用于控制该生产过程就能够获得专利保护。也就是说，智力活动规则和方法本身不被授予专利权，但进行智力活动的机器设备、装置或者根据智力活动规测则和方法而设计制造的仪器、装置等都可以获得专利保护。即软件和硬件或者工业产品结合并表现为机器、装置或者为达到某种结果表现为方法时，软件可成为专利保护的对象。
（）指可以不经著作权人许可，不需支付报酬，使用其作品。
- A. 合理使用
- B. 许可使用
- C. 强制许可使用
- D. 法定许可使用
【试题解析】∶合理使用是指可以不经著作权人许可，不需支付报酬，使用其作品;许可使用是指在获得著作权人许可后使用其作品;强制许可使用也称为强制许可或非自愿许可，是指国务院专利行政部门依照法律规定，可以不经专利权人的同意，直接允许申请人实施专利权人的发明或实用新型专利的一种行政措施;法定许可使用是指法律明文规定，可以不经著作权人许可，以特定的方式有偿使用他人已经发表的作品的行为，并且这种使用应当尊重著作权人的其他各项人身利和财产权。
下列关于软件著作权中翻译权的叙述不正确的是:翻译权是指（）的权利。
- A. 将原软件从一种自然语言文字转换成另一种自然语言文字
- B. 将原软件从一种程序设计语言转换成另一种程序设计语言
- C. 软件著作权人对其软件享有的以其它各种语言文字形式再表现
- D. 对软件的操作界面或者程序中涉及的语言文字翻译成另一种语言文字
【试题解析】∶软件著作权中翻译权属于软件著作财产权，是指将原软件从一种自然语言文字转换成另一种自然语言文字的权利，而不是指将原软件从一种程序设计语言转换成另一种程序设计语言。
下列标准代号中，（）为推荐性行业标准的代号。
- A. SJ/T
- B. Q/T11
- C. GB/T
- D. DB11/T
【试题解析】∶依据我国标准化法”，我国标准可分为国家标准、行业标准、地方标准和企业标准。其中，国家标准、行业标准、地方标准又可分为强制性标准和推荐性标准。它们分别具有其代号和编号，通过标准的代号可确定标准的类别。行业标准是由行业标准化组织制定和公布适应于其业务领域的标准，其推荐性标准，由行业汉字拼音大写字母加T组成。已正式公布的行业代号有Q3(航天)、SJ(电子)、JB(机械)和JR(金触系统)等。试题中给出的供选择答案，分别依序是行业推荐性标准、企业标准、国家推荐性标准和地方推荐性标准。
以下作品中，不适用或不受著作权法保护的是（）。
- A. 某教师在课堂上的讲课
- B. 某作家的作品《红河谷》
- C. 最高人民法院组织编写的《行政诉讼案例选编》
- D. 国务院颁布的《计算机软件保护条例》
【试题解析】∶根据我国《著作权法》的规定，有三种类型的作品不受法律保护。第一种是依法禁止出版、传播的作品。第二种是不适用于《著作权法》的作品。它们包括下列作品：
(1）法律、法规，国家的决议、决定、命令和其他具有立法、行政、司法性质的文件，极其官方正式译文；
(2）时事新闻;
(3）历法、通用数表、通用表格和公式。
国务院颁布的《计算机软件保护条例》属于法律法规，所以不受著作权法保护。
甲、乙两公司的软件设计师分别完成了相同的计算机程序发明，甲公司先于乙公司完成，乙公司先于甲公司使用。甲、乙公司于同一天向专利局申请发明专利。此情形下，(）可获得专利权。
- A. 甲公司
- B. 甲、乙公司均
- C. 乙公司
- D. 由甲、乙公司协商确定谁
【试题解析】∶依据《中华人民共和国专利法实施细则(2O10修订)》，第四十一条两个以上的申请人同日(指申请日;有优先权的，指优先权日)分别就同样的发明创造申请专利的，应当在收到国务院专利行政部门的通知后自行协商确定申请人。
本题注意与商标权的确定规则区分开来，商标法是同日申请，先使用者获得，无法举证时，抽签决定，专利法，则不看是否先使用，直接协商。
以下著作权权利中，（）的保护期受时间限制。
- A. 署名权
- B. 修改权
- C. 发表权
- D. 保护作品完整权
【试题解析】∶保护期限不受限制的有∶署名权，修改权，保护作品完整权。保护期限为作者终身及死后50年的，包括:发表权、使用权和获得报酬权。
某软件公司参与开发管理系统软件的程序员张某，辞职到另一公司任职，于是该项目负责人将该管理系统软件上开发者的署名更改为李某（接张某工作)。该项目负责人的行为（）。
- A. 侵犯了张某开发者身份权（署名权）
- B. 不构成侵权，因为程序员张某不是软件著作权人
- C. 只是行使管理者的权利，不构成侵权
- D. 不构成侵权，因为程序员张某现已不是项目组成员
【试题解析】∶根据《中华人民共和国著作权法》第9条和《计算机软件保护条例》第8条的规定，软件著作权人享有发表权和开发者身份权，这两项权利与著作权人的人身是不可分离的主体。其中，开发者的身份权，不随软件开发者的消亡而丧失，且无时间限制。张某参加某软件公司开发管理系统软件的工作，属于职务行为，该管理系统软件的著作权归属公司所有，但张某拥有该管理系统软件的署名权。而该项目负责人将作为软件系统开发者之一的张某的署名更改为他人，根据《计算机软件保护条例》第23条第4款的规定，项目负责人的行为侵犯了张某的开发者身份权及署名权。
有可能无限期拥有的知识产权是（)。
- A. 著作权
- B. 专利权
- C. 商标权
- D. 集成电路布图设计权
【试题解析】∶其中商标权可以通过续注延长拥有期限，而著作权、专利权和设计权的保护期限都是有限期的。
甲公司购买了一工具软件，并使用该工具软件开发了新的名为“恒友'的软件。甲公司在销售新软件的同时，向客户提供工具软件的复制品，则该行为（），甲公司未对恒友"软件注册商标就开始推向市场，并获得用户的好评。三个月后，乙公司也推出名为"恒友的类似软件，并对之进行了商标注册，则其行为（）。
问题一
- A. 侵犯了著作权
- B. 不构成侵权行为
- C. 侵犯了专利权
- D. 属于不正当竞争
问题二
- A. 侵犯了著作权
- B. 不构成侵权行为
- C. 侵犯了专利权
- D. 属于不正当竞争
【试题解析】∶第一空，涉及向客户提供工具软件的复制品，这里侵犯了工具软件的著作权;
第二空，甲公司没有注册商标，并且没有描述商业秘密相关内容，所以不涉及商标权保护和不正当竞争法保护，而著作权是自作品完成之时就开始保护，所以甲公司当软件产品完成之后，该作品就已经受到著作权保护了，乙公司的行为侵犯了著作权。
按照我国著作权法的权利保护期，以下权利中，(）受到永久保护。
- A. 发表权
- B. 修改权
- C. 复制权
- D. 发行权
【试题解析】∶本题考查著作权的保护期限问题。
著作权中修改权、署名权、保护作品完整权都是永久保护的。
