Dive into the search process, requirements for documentation (Rule 35), and handling unity of invention challenges (Rule 40). Part 3: International Publication Understand how applications are published internationally under Articles 20–21. Learn about publication languages, corrections (Rule 91), and managing the contents (Rule 48). Part 4: National Phase Entry Master the transition from the international to the national phase, guided by Articles 22–27 and Rules 49 and 51. Discover how early processing and other procedural requirements are handled. Part 5: International Preliminary Examination Gain insights into the Chapter II process, including patentability criteria (Article 33), demand requirements (Rule 53), and the International Preliminary Report on Patentability (Rule 70). Part 6: Unity of Invention & Fees Learn about unity of invention rules embedded in Articles 15, 17, and 33. Explore the impact of additional fees under Rules 13, 40, and 68 on both the search and examination phases. Part 7: Restoration of Priority Manage priority claims under Articles 8 and 24. Learn remedies for missed deadlines (Rule 82bis) and corrections of priority claims (Rule 26bis). Part 8: Withdrawal & Amendments Find out how to make amendments under Article 19 and withdraw international applications or demands using Rules 46 and 90bis. Part 9: Roles of WIPO, ROs, ISAs, IPEAs, and IB Discover the responsibilities of key players in the PCT system under Articles 16, 31, and 52, including Rules 93 and 94 governing access to files and the International Bureau’s roles. Part 10: Language, Disputes & Transitional Provisions Learn about language requirements, dispute resolution, and transitional provisions under Articles 44–67, with Rule 92bis guiding applicant detail changes. The design and development of this iOS app, including the preparation of the legal questions, were carried out by Barış ATALAY, an EQE tutor and iOS developer (not professionally). Feedback regarding the legal questions or the app's SwiftUI implementation is welcome. You can reach Baris at atalay@stanadvoka.com.

Calculus Practice is an educational application designed to help students strengthen their understanding of calculus through structured practice questions. The app provides chapter-wise quizzes, mock tests, and daily practice questions covering key calculus topics. Students can practice conceptual problems, solve numerical exercises, and track their progress using statistics. The app supports independent learning and systematic revision of fundamental calculus concepts used in mathematics, engineering, and science courses. Topics Included 1. Limits and Continuity Concept of limits, left-hand and right-hand limits, limit laws, continuity of functions, and different types of discontinuities. 2. Derivatives and Differentiation Derivative definition, differentiation rules, higher-order derivatives, implicit differentiation, logarithmic differentiation, and differentiability conditions. 3. Applications of Derivatives Rates of change, increasing and decreasing functions, maxima and minima, tangent and normal lines, linear approximations, and curve sketching. 4. Indefinite Integrals Concept of integration, standard integration formulas, substitution method, integration by parts, partial fractions, and trigonometric integrals. 5. Definite Integrals Definite integral concept, fundamental theorem of calculus, properties of definite integrals, area under curves, substitution methods, and evaluation techniques. 6. Applications of Integration Area between curves, volume of solids, surface area of revolution, work done calculations, average value of functions, and physical applications. 7. Differential Equations Definition of differential equations, order and degree, separable equations, homogeneous equations, linear differential equations, and practical applications. 8. Advanced Calculus Concepts Series expansions, Taylor and Maclaurin series, improper integrals, multivariable functions, and partial derivatives. Key Features Chapter-wise calculus practice quizzes Mock tests for overall assessment Daily quiz for regular practice Performance statistics to track progress Clear topic organization for systematic study Simple and distraction-free interface Calculus Practice is suitable for students studying calculus in mathematics, science, and engineering courses who want structured practice and regular revision.
