1. Invention patent: refers to a new technical scheme proposed for a product, method or its improvement.
2. Patent for utility model: refers to a new technical scheme for the shape, structure or combination of products, which is suitable for practical use.
3. Design patent: refers to a new design that is aesthetically pleasing and suitable for industrial application in the shape, pattern or combination of product and the combination of color, shape and pattern.
It usually takes about 3 years to grant the invention patent.
5. It usually takes about 1 year to grant a patent for utility model.
6. It usually takes about 8 months to grant a design patent.
Classification level:
The international patent classification adopts hierarchical classification structure, which expands all technical fields step by step according to six levels-department, division, class, subclass, group and group, forming a complete classification system. For example, in the eighth edition, all technical fields are divided into 8 departments, 2 1 division, 120 categories, 628 subcategories, about 7,000 large groups and about 62,000 groups.

Classification of evaluation indexes of enterprise patent management:
(1) evaluation element.
Evaluation element is the basic unit of the evaluation object and the main requirement of the appraisee's work. Evaluation mark is the embodiment of the key distinguishing features of evaluation elements, and it is the characteristic regulation used to distinguish all levels in evaluation indicators.
According to the forms of expression, evaluation marks can be divided into three types: comment short sentences, question prompts and direction instructions. Comment short sentences are sentences in which the evaluation elements judge and comment on the merits, the merits, the size and so on. Questioning and prompting are to prompt the evaluator to master the characteristics of evaluation elements in the form of questioning.
Directional indicators only specify which aspects to evaluate, but not the marks and scales of evaluation, so that the evaluation subject can grasp them as appropriate.
(2) Evaluation scale.
The forms of evaluation scale can be divided into the following four types: quantifier evaluation scale. This scale uses adjectives, adverbs, nouns and other phrases with different degrees to express different grades. Such as "more", "more", "general", "less" and "less"; Good, good, fair, poor, poor. Graded evaluation scale.
This scale refers to some words, letters or numbers with clear rank order indicating different evaluation grades. Such as "excellent", "good", "average" and "poor"; A, B, C and D. Quantitative evaluation scale. This scale is expressed by fractions and can be divided into discrete and continuous.
Authoritative evaluation scale. This scale uses words to specify the range and level difference of each scale. Compared with the first three evaluation scales, the defined evaluation scale is more complex and specific.
(3) Evaluation scale.
The evaluation tag specifies the range of evaluation elements at each level. The scores and scales of government performance evaluation indicators are one-to-one correspondence. Marks are simplified proportions, while proportions are concrete and detailed. When the scale itself is simple, the sign and scale can be combined into one. The key to distinguish different evaluation marks is in what form the evaluation marks stipulate the standards that should be based on in the evaluation elements.
